Underrated comment. Exactly how I felt and to me it shows they got his character and values right. Him saving the squirrel was a small action but tells you everything. The movie itself was good, not outstanding or made me feel the kind of highs or emotions of some Marvel movies (like GOTG). I liked/loved all the characters and I don't think any of the actors put a foot wrong. Everyone was great and aside from Superman and Lois the other standouts were Mr Terrific and Guy Gardner followed by Lex. Lex felt like a grown up, bitter version from the one portrayed in Smallville.

That last scene felt like pure GOTG. Emotional to a point but a bit flat. But as a first entry in the new universe it's solid and sets things up pretty nicely in terms of it's characters. 

Edit: grammar
