Spoiler: Thought it was a very solid conclusion to the first three phases of the MCU
The first hour or so I found quite slow, aside from the death of Thanos - which was a massive shock - nothing much happened, apart from setting up where everyone was and what mindsets they were in
The time heist was quite fun, I do appreciate the fact that the mission/reset button wasn't to undo what happened in Infinity War, but to bring everyone back five years later. So Thanos' actions still happened, and the consequemces still exist. I would imagine these will be elaborated on in the upcoming season of Agents of SHIELD
Clearly the best scene was the return of all the heroes at the end, and the ensuing battle. I do wish they had shown some of the rest of the world/universe as that happened though. We saw a snapshot of the deaths at the end of IW, would have been nice here too, but again, we should see this in AOS
Loved some of the call-backs to previous movies, my personal favourite being Cap using Mjolnir and Thor saying he knew he could do it - remember when he nearly lifted it in Age Of Ultron?
Have to admit to getting a little misty-eyed at Stark's funeral, but tbh we all expected there would be a big death, so while it was definitely emotional, it wasn't a massive surprise
Funniest reaction from the audience was a collective groan when Fortnite made an appearance :p
Minor gripes, but Thanos was only able to use the Gauntlet because of 'space magic' as Thor put it, right? So how could Stark suddenly make a glove that worked just fine?
Also, Captain Marvel is one hell of a deux ex machina to have around, isn't she? ;)
I really have to many favourite moments to pick out, but as you've already mentioned Spoiler: Cap finally wielding Mjolnir, also the Spoiler: Cap standing all alone against Thanos's army, then Cap do you read, it's Sam, on your left, Spoiler: even listening to the song on the soundtrack that builds during said scene, I can picture it clearly the screening where I was at, absolutely bubbled up ready to explode... And then we FINALLY got those words from Cap Spoiler: Avengers... Assemble, and charge with Cap at the front, cue the explosion from the audience.
I don't think the films events will be touched on in Agents Of Shield's upcoming season, think the earliest we'll get those events being referenced is the Spider-Man: Far From Home - Spoiler: Also I think said film will pick up where Peter and Ned reunited in Endgame
Spoiler: Tony's death, absolutely caught me right in the gut/feels, especially with how he uttered the line that kicked this all off 11 years ago today
