A few people have mentioned this being the "ultimate" summer or year for genre pictures. On the one hand I'm thinking it could be but on the other I do agree that all the big movies this year are just part of a series we've already seen or are reboots.
And quality wise I'm not convinced that ANY of these movies will top their predecessors.
I think it will very likely turn out that:
Captain America: The First Avenger > The Avengers
Spider-Man 2002 > The Amazing Spider-Man
The Dark Knight > The Dark Knight Rises
Alien > Prometheus
The Lord of the Rings > The Hobbit
I think the only real guarantee of a movie this year topping its predecessor is GI Joe. Now before anyone freaks out I readily admit that ALL of this year's movies could be the best version yet of their respective stories and that of course would be the coolest thing ever. But otherwise this year just might be a ton of movies with characters that we've already seen in better films. I hope not.
