I wrote this on the X3 forum when someone said an episode of Heroes was similar to a truck flipping scene in X3. I think what I said applies here too...
As a musician, it's often easy to end up having a riff or a song sound strikingly similar to other songs/riffs. This isn't on purpose. As an artist inspired by other artists, my head stores all of my creativity in the same place it stores all of my loves and interests.
It's possible that as superhero show, the writers unintentionally had similar ideas to X-Men (like the truck flipping sequence). I don't believe for a second after watching the abomination that was X3, any one thought, "Hey let's re film that sequence for OUR movie!" That scene is not that great to begin with. I think anyone shooting an action film or show is inspired by other action films/tv shows that aren't mutant themed. I mean seriously, is X3 the only movie you've seen?
Also, any intentional similarities to Watchmen, X-Men, or JLA are fine by me as I don't think it is possible to ever get any of these stories captured exactly how it was when I first read the classic issues so why not pay homage to them? That way there's no insistance on accuracy and a new generation can enjoy the benifets of a classic story line they may not be able to get behind otherwise because the reason why these stories are often so great is that they relate to the times they are written in and are meant to parrallel current events.
Furthermore, comics/superheroes are just recycled myths and greek heroes re-invented for our times to be relevant to our lives today. I don't think the story of Superman takes anything away from Hercules at all, they are both great in their own right. I agree that movie ideas today have certainly dwindled into a nastalgia fest but I also think that is the problem with fans as well. I mean movies are going to be different than their comic counterparts whether or not your nastalgic feelings are hurt or not. I mean if I went to this great bbq my dad held in our backyard in 1988, am i going to go back to that house and re create the same benches and tables, de-age all of my dad's friends and make them talk about George Bush sr. choking on a some chicken in Japan, bring my dead dog back to life so he can bark at my neighbors, and make sure that we're all wearing the same clothes? NO! But if I did want that bb-q I would just find the receipe and make sure it tastes just as good as it can be.
I got off topic but seriously I really feel like you guys are nitpicking here. Heroes, despite it's glaring plot holes, character flaws, inconsistent acting, terrible season 1 finale, and akward season 2 pacing is a pretty damn good show. Stop acting like X Men 3 didn't make you want to gauge out your eyes and watch a show that at least can make up for it's mistakes in the next episode.
