I'd heard some stuff from my friend, so I wasn't really thrilled going into it. It had some great parts, and themes about family. (Some people made up. I won't say who. Spoilers.

Guardians of the Galaxy 2: There was some really cool stuff in there. (Nebula was actually interesting as opposed to the earlier movie where she was just basically baddie #3) I began to care more about characters I never thought I would. Yondu for the win, man. But overall, I feel disappointed. But other parts of it just felt like a bigger grungier version of trying to top the first one. I guess (even though I liked Thor 3 alot ) I can't stop being disappointed in the movie creators.
Spiderman: Homecoming on the other hand, that I enjoyed much, much more. Even if I did alternate between cheering for him and covering my face in second hand embarrassment. (Except for that one part where I wanted to give him a talking too.) But I felt it was believable considering he's trying to handle life and being a teen with this new cool experience he's just had. (I'm still kinda sad about Peter and Liz.)
