Sorry, this is legitimately how I feel. And no, I'm not trolling. I have to make that clear because people always cry wolf about that.
(1) Trying WAY too hard to be funny, which is frankly expected from an MCU film at this point. It was cute in the first Iron Man. It fails when you apply it to Doctor Strange, and it fails when you shoehorn jokes that are entirely unnatural for Peter. "Heeeey... You guys aren't the real Avengers!" It's just a line I can tell was thought up in some Corporate boardroom.
(2) Actor for Peter sucks boiled eggs. Seriously, he's awful. The issue I have with him is the same one I have with Hemsworth, Eisenberg, Evans, and Amy Adams. You can tell they're putting on a performance. Maybe it's the way they carry themselves, or how they deliver their lines, but there's just something there that constantly reminds you, "Hey, that's not Thor! That's Hemsworth with a crappy accent!" Peter's actor came across this way.
(3) Have absolutley zero interest in HS drama Peter Parker. Can we please just get adult Peter back? Thanks.
(4) MCU movie plot continues to look generic without breaking any mold. It's ok to have an "MCU flavor" for their brand, but it's as though they're all the same film with different coats of paint. Look, instead of magic, Peter has webs! Instead of being Nazis, the bad guys taking over the world are Nazi ALIENS! It gets old.
Just my thoughts. To say the least, I wasn't pleased.
