- Heroes - I loved this show. Through and through. The first two seasons were definitely better and the show waned as it went on, partly I think due to the writer's strike which, if that would not have happened, would have greatly influenced the storyline of season three. But I still thought it was incredibly interesting right up until the end of the fourth season when it stopped abruptly with a "to be continued...". There were talks that it would get a two-hour TV movie conclusion but that never materialized, sadly. The characters and stories were extremely interesting and brilliant. The only thing I really complain about is the fact that we never ever got to truly see a whole complete fighting seen without hiding it behind a closed door or portraying it with flashing lights from a keyhole. And that's something every superhero movie or tv show needs. Yes, it was a show about people more than special effects, but we should have had some decent fighting scenes. I actually think that Heroes would be a perfect candidate for Telltale Games to pick up and expand upon. And seeing that it's owned by NBC Universal (who granted Telltale licenses to Jurassic Park and Back to the Future) it seems like a nice match. That's one game that I wouldn't care how cinematic it would be simply for the fact that I so badly want to see what happens in Volume 6! Assuming it's done well.
- The Dead Zone - Based on Steven King's original story. Another show I just adored. It wasn't so much with that horror aspect that King is known for but with elements of thriller, suspense, science fiction, and even a detective show in a way. It also started to lose quality, intrigue, and in this show's case, it's unique sense of surreal atmosphere it maintained in the first three seasons. But I think this was mostly due to the fact that Michael Piller, the man who created the show, died of cancer after the third season. The last season (6th) was again supposed to go on for one more season but it was axed early and we never got to see what was going to unfold with Stilson and Armageddon (what a perfect rivalry and awesome chemistry between Johnny Smith and Stilson! I loved every scene of them together). Anthony Michael Hall and the supporting cast were brilliant and played their roles perfectly. The network cancelled this along with The 4400 to make room for "more original shows"....like yet another variation of CSI or Law & Order or a reality show of some nature.
- Stargate Atlantis - This was a great show. Better than SG-1, in my opinion. The sci-fi feel just felt more fitting than SG-1. I enjoyed the fact that it was based a lot more on Atlantean myth rather than Egyptian, even though SG-1 weaned away from Egyptian and embraced a lot of other lore as it went on, mostly after season 5 I think, which interestingly was when the show was handed off to Fox from Showtime. Anyway, the last season of Atlantis was slightly under average from the first three, but it still had a lot of great moments. It ended well enough (if simply), but a movie follow-up was promised to explain a lot of the loose ends (much like how The Ark of Truth did for SG-1) but because of the economy and the fact that TV DVD sales were plummeting for some reason (according to Fox) it never happened. SG-1 had a bit of a dumb ending as well, but it went on for 10 years so it's not like they couldn't have gotten it right. And they did get two movies afterwards which tied up all loose ends and even had room to tell a completely unrelated story just for the fun of it.
Also, I hated Stargate Universe and I'm glad it was cancelled.
- The X-Files - Though this show wasn't really cancelled per se, it did end off with a handful of unanswered questions. Whatever happened to the cloned alien bounty hunter? Whatever happened the hybrid alien that was evolving in that power plant with Gibson Praise? Speaking of which, how did Gibson ever get out of there and end up at a school for deaf kids in the middle of the desert? How did Crychek (I'm probably getting the spelling of these names all wrong, btw) escape from that missile silo? I know it explained it that some freedom fighters or something "found him" and he joined with them, but what were THEY doing in those silos miles underground? Just slightly annoying. And whatever happened to Dogget and that other chick at the end of the series finale? They just drive off and we never hear from them again. Not even in either of the two movies. And what happened to Skinner in the finale when he walks into the room with the alien hybrids with that forboding feeling of him never coming out of there alive....and then we see him in the second film just fine. What about the fact that certain mestizo people (descendants of the Anasazi tribe or something who encountered the aliens and disappeared without a trace) were immune to the black oil? Why wasn't that ever expanded upon? The ending of the show was decent enough I suppose, though. The best way you could close it off. Just a lot of annoying loose ends that never were explained. Unlike most people, though, I preferred the alien conspiracy stories over the random generic paranormal stories.
- Firefly - I never got into this show but I've seen a few episodes which were quite good and I of course saw and loved Serenity as well. But a lot of people adore this show. The idea of its cancellation was a blasphemy and a sin to many many people. Moreso seemingly than any other cancelled show out there.
On the flip side, one of the shows I'm still interested in now and that is still going on is Eureka. It seems like the kind of show that would get cancelled, but I'm glad it isn't because it's fantastic. Great cast, great stories, great sci-fi. It's like The Andy Griffith show meets Star Trek or something.
