Immediate thoughts (1 hour after leaving the cinema) is that I really enjoyed it and am looking forward to watching it again on Saturday.
Someone mentioned Kill Bill 1 & 2 and I agree it felt a bit like that. Infinity War is more action heavy, and this is a lot more talky. I've said before that at this point I could watch most of the cast sitting around chatting in character, and the first hour certainly felt like that is what they had done.
I'm interested how it's going to play with the younger fans. My best mate has boys aged 4 and 8 who love these movies but I can't imagine them enjoying this as much.
Pros:
The feels - I felt my eye getting a bit wet at least twice. Once when the resurrected people showed up through the portals and especially with the "Love you 3000" line near the end from Tony. I've had goosebumps before watching some of these movies (Thor: Ragnarok "I'm the goddess of death. What were you the god of again?") (Infinity War - Thors arrival back on Earth) but it's never really upset me before
Thor and the humour in general - The first hour not a lot tickled me, but as soon as Fat "Big Lebowski" Thor was on screen his stuff was absolute Gold. He was the MVP of both Infinity War and End Game, and though I thought he was done with the MCU, him being part of the (As)Guardians of the Galaxy would be so good. That end scene between Quill and Thor absolutely killed me. Also Professor Hulk and Scott Lang in the diner with the selfies was hilarious. And Prof Hulk halfheartedly smashing the taxi roof and throwing the moped
Mehs:
I've been called a white knight SJW on this forum before, but I thought literally
all the women of the MCU suddenly being their to help Captain Marvel get the Infinity Gauntlet through the hordes in front of her was a bit too on the nose....Captain Marvel kicked arse though.
Scott Lang being retrieved from the Quantum Realm by a rat.
Things I am very unclear on:
1)You can't change the past, but Captain America got to go back for his dance with Peggy and married her...and that doesn't change anything?!
2) Where did Thors hammer come from? Did he take it back from Asgard 2013? And wouldn't that then spew off a timeline where lots of bad things happened because the hammer was missing? (As The Ancient One demonstrated)
EDIT - Just realised Captain America likely dropped it back at the exact point it was taken)
3) The 'dusted' people were bought back 5 years on from their deaths, but exactly as they were. That going to be
really awkward if your other half really had moved on with their lives and married someone else, or died of natural causes?
