re: Life of Chuck
I actually just watch this for the second time and I would definitely recommend it. It is a movie that could have very easily been terrible if it was handled just slightly differently, but at least for me the executed it perfectly.
re: Superman
Personally I really enjoyed Superman. I thought it was fun and I liked the focus on Superman as just a really caring person above all else. I also thought all of the performances were good. I think it's funny that even when trying to make a solo superhero movie like that James Gunn just couldn't stop himself from kind of making it an ensemble.
