i'm gonna quickly address those other movies i talk about
blair witch project (82% on rt): nothing happens in this movie, it 79 minutes of walking around,vary little character development and occasionally something scares cast but not audience because it doesn't show the scares
back to the future (97% on rt):its not a bad film but its not this end all be all of film ,its a silly family film with time travel plot, it has a few quotable lines and one or two memorable characters and most of the praise that this movie gets come from rose colored glasses
dark knight rises (87% on rt): i agree with most of what this guy says, so watch this video
Overall, I agree. Although it has been so long since I saw the Blair Witch Project that I can't comment on it. However, I don't remember it being good.
For Back to the Future, I view it as one of my favorite movies, but not because it is a particularly good movie. It is good. But more than that, it embodies an entire genre of movies that existed only in the 80s. Seriously, we just don't get those movies any more (Super 8 was pretty close in that it was a love letter to these movies).
I really liked the Dark Knight Rises. However, I am not too sure how well it will age. Most superhero movies don't. But I think it gets the same acclaim that Return of the King did. It may not be the best of the movies. But it wrapped up a very good and celebrated (rightfully imo) trilogy.
I also have to put Batman in the context that Bruce Campbell put superhero movies in... they are B movies. It does not matter what the budget is, it is about a dude who dresses in an animal-inspired suit to fight crime. That's a B movie. It isn't Citizen Kane, nor is it trying to be. It is a B action movie, and it does this job exceedingly well.
