Underwhelming

Rating: 6/10 (28 April 2019)

Endgame consistently felt off from the start to the end. The tone is just strange, the pacing is messy and the plotholes are ridiculous and badly effect the enjoyment of the film. That said there are some fun scenes.
This felt more like a tying up of loose ends rather than a real self-contained film. While I liked Infinity War they really backed themselves into a corner when they got time travel involved. So many plot holes and convoluted plot lines concerning time travel.... How is Captain America able to come back at the end if he has gone to a different time line? This is a direct contradiction of something they said previously in the film - that going back into time does not change the future. But, lo and behold, Captain America is suddenly in this very timeline, but somehow without affecting it? This makes no sense.
How does Captain Marvel know where Tony Stark is??! In the vast endless expanse of space she somehow randomly comes across him!!? This is never explained.
Stark figuring out time travel in about 2 minutes is just laughable.
How can Thanos be so powerful without the infinity gauntlet so that he can easily defeat Thor, Iron man and Captain America all at once?!? This was the most fun fight scene by far but it is partly ruined by its illogical premises. Reminds me of Star Trek Discovery where we are supposed to be dazzled by the spectacle and not take plot continuity seriously anymore.
As other people have pointed out they ruined the character development they had set up with Thanos' character. This wonderfully rich character is killed in the first 5 mins of the film. Only to be replaced by his more one dimensional past self later. It might as well have been any generic bad guy. There is no satisfying link to the Thanos of the first film.
Fat comedy Thor really disrespects his character and just looks and feels so silly. They could have made him depressed and overweight sure, but why make it so pronounced that it becomes hard to take seriously. He has become a (bad) parody of himself. I like the comedy element of these films but please take it back a notch.
The interactions between Stark and Rodgers seemed stale and repetitive. It was hard to care anymore. I actually liked the Hulk/Banner hybrid - this was one of the more inventive/original parts of the film. It would have been good to see him actually fight! I liked the interactions between Hawkeye and Black Widow. Their relationship has always been interesting/layered and well acted.
The final battle scene felt like a rehash of the one in Wakanda. So, again, hard to get excited about something we have seen before. But of course, it has its fun moments. I loved seeing Scarlet Witch take on Thanos one on one and get the better of him until he calls on the big guns.
It seems like the story line of IW bit off more than it could chew. It becomes so overblown and fantastical that it is hard to take seriously anymore. A bit of an anti-climax. But of course its still a must-see because its the culmination of a decade of Marvel films. I still enjoyed this film to an extent, its just a bit disappointing. I could have easily sat through another hour of this if it helped sort out the pacing problems and made more sense of things.
