TIH established that Banner could "aim" the Hulk and then showed him deliberately triggering a change. He did both of these things in his second transformation in The Avengers. It's not as simple as Banner controlling or not controlling the Hulk, all or nothing.
Fair point, but I've always interpreted the final scene in TIH to be a much stronger form of control. That's where I felt the sequel was going, but I admit it does not explicitly confirm my assumption.
Thor - 9/10
Might actually be my favorite Phase 1 film. Best villain of the MCU with Loki. Good motivations, good plan and an excellent actor to bring it all together. Thought the humor with Thor on Earth was good, and I even like Darcy's silliness. Substantial and natural character development for Thor. I don't even have a lot of nitpicks about this one.
Captain America - 7/10
Cap's my favorite superhero and I like a lot of things here. Skinny Rogers is great and I'm glad they spent the time really introducing the character. I love Atwell and have always felt that she and Evans had the best chemistry of the couples. Stanley Tucci also turns in a great performance(no surprise there).
Unfortunately, the Red Skull comes off as another poorly developed villain. I really wish they would have planned out a more coherent philosophy for HYDRA. Also, the movie is a bit montage-y but I can understand why. Some of the CGI is a little sub-par as well, especially the Landkreuzer.
Annoying nitpick:
1)How fast is the flying wing going to get from the Alps to anywhere near North America? Mach 5?
2)This is a pretty major plot point, so maybe not really a nitpick, but why does Cap need to crash the plane himself? Why cant he just jam something on the stick and bail out? He can clearly steer the plane, why not just fly in circles until some kind of rescue plan can be put in place?
Avengers - 10/10
Still my perfect superhero movie. Really feels like a comic book, especially how when any to superheroes meet for the first time what have they got to do? Fight of course! Humor was good, action was great and almost every character got some good scenes(almost, poor Hawkeye). It's not a deep movie, but it doesn't have to be. It's all about seeing these guys all come together and kick butt.
Iron Man 3 - 9/10 - I'm apparently in the minority but this is actually my favorite Iron Man movie. The Mandarin and Killian actually felt threatening enough that I wanted to know how the hero would win, not just when like the other movies. Love the Mandarin twist(even if I saw Killian being the big bad from a mile away). Great sense of humor, easily the funniest MCU film for me. Heck, they even made me like the kid sidekick.
Thor: The Dark World - 5/10
My least favorite MCU.
Malekith is another terrible villain. He's pasty and wants to destroy the universe. That's about all we know, and he has like 10 lines in the whole movie. He makes Red Skull and Vanko seem sophisticated and interesting. Also didn't like most of the humor in this one( I especially hate when Thor destroys the big rock monster, and says "Anyone else?"

hilarious). It doesn't help that the movie is very visually dreary, no offense to Londoners but maybe next time we could film in a less overcast city?
