List of complaints
I liked the movie. Didn't love it. Some minor and major complaints. Obviously SPOILERS!
1. The subtleties of Thanos's character are discarded and replaced with full-blown evil.
2. Cap chooses to abandon fighting with his team to protect the Earth in the present to stay back in history with Carter which is a fuck you to the Avengers, Carter's husband-to-be, and to the people of Earth-present-day. Also flies in the face of established rules set in the movie.
3. Ant Man and Wasp go to use the time travel machine in the bus mid-battle. They make a big deal about it but nothing happens.
4. To get the Soul Stone you have to "sacrifice something you love" but then it just turns out you have to simply serve up a warm body. The scene was as bland as Johanson's portrayal of BW for the entirety of the run.
5. I was hoping to like Cpt Marvel more in this. I expected the Russo brothers to make me like her, unlike her solo movie. I did like her intro scene in the big battle but again, huge power levels followed by her conspicuous absence. Felt edited-in in post. Still unhappy with the actress. Looks much better with the short hair.
6. Parker is gone for 5 years and all of his high school class mates are still in school?
7. Thanos was nearly killed when he used the stones to destroy the stones; not for simply using them. They seemed to forget this and had Tony suffer from that for plain "use"
8. How did Cap replace the Stones that were in space/Asgard?
9. Where did Thanos's massive army invasion shards come from in the end? They looked as big as his ship.
10. Thanos's personal villain crew were dispatched too easily. Giant Man stomps one and it's over for him, etc.
Plenty of cool scenes and I did enjoy myself. Would have liked quite a few things done differently. Movie felt messy, editing-wise and continuity.
