Nope, I actually enjoyed Gangster Squad more so than I ever did with any of the Iron Man films. Gangster Squad is a flawed movie, but I liked it all the way however it's not memorable or anything. I'll probably forget it in a few weeks time though.
Saw Thor earlier in the week in one of my classes, and to my surprise, I really liked the movie. It's not spectacular, but I had fun with the film since I thought it was charming at times. I'm not pumped for Thor 2, but I wouldn't mind paying full price for it if it's like its predecessor.
