Hmm, okay,I'll try and play along--even though I think scoring in such a way isn't always accurate and generalises somewhat. First I'll just write a list and try to organise it from there.
Avengers
First Class
The Dark Knight
Watchmen
Thor
The Incredible Hulk
Batman Begins
Spider-Man
Spider-Man 2
Batman 89
Okay, I've just tried scoring, but didn't like the way it looked. When you have a list like this, it's very hard for your scores to make sense. I did it as honestly as I could, but when looked through I honestly didn't think it was an accurate representation of my tastes.
For simplicity sake, Avengers is top, followed by First Class. I like TDK, and also Burton's 89. Thor wowed me. Never liked the character but I enjoyed it. Hate Cap. Can never decided whether I prefer Spidey 1 or 2, but more often than not I'd probably go for Spidey 1 for tone, and Spidey 2 for action. Some are hard to score together because they are so different. Am I scoring for enjoyment or for understanding how well made they are? You get me? It's a very hard subject for me because my tastes are so wide, and I wouldn't really be comfortable setting these scores in stone, and putting one film above another because when my mood changes, so does my opinion.
Edit: S*** I forgot Sin City
