Cap looks good! Way better than expected. Ranking my anticipation for the summers Super Hero slate, I'd have to say X-Men->Cap->Thor->Green Lantern. I don't think Green Lantern necessarily looks poor, we just haven't seen much apart from a mediocre trailer that couldn't settle on a tone.
Also, I'm going to join the party as well:
Note: In each category, films proceed from best to worst
Great
The Dark Knight
Batman Begins
Spider-Man 2
X-Men 2
Superman
Good
IronMan2
IronMan
Spider-Man
Hellboy 2
Batman Mask of Phantasm
Superman 2
X-Men
Hulk (sucker for how Ang Lee tackled this one)
V for Vendetta
Sin City
The Incredible Hulk (barely makes this category to be honest, I find it meh but it is technically well done. Especially the segments in Rio)
300
Superman Returns
Blade 1&2
Unbreakable (liked it more when I could bear popping a Shyamalan movie in my dvd player)
Average
Watchmen
Hellboy (Just not my cup of tea. Loved the sequel)
Batman Returns
Batman
Constantine
Not much fits this category for me. I find the genre to be particularly love it or hate it.
Awful
X-Men The Last Stand
Daredevil (directors cut elevates it to average)
Fantastic Four 2
Spider-Man 3
Wolverine
Batman Forever
Fantastic Four
Both of the Punishers.
Blade Trinity
Superman 3 and 4
Elektra
Batman and Robin
Ghost Rider (fucking can't stand this movie)
Catwoman
Am I missing anything? To be honest I'm only really passionate about the Nolan Batman films. I follow Marvels current slate with a lot of interest, but I still don't think they've topped their first couple of sequels (X2, Spider-Man 2). The Iron Man movies are fun. I think the first is a touch overrated, and the second is a touch underrated. To me they play like 1 very fun 4 hour long movie.
