Even non-MCU fans HAVE to watch this.

Rating: 8/10 (28 April 2019)

You know what surprised me the most about this film? It's that it had some minor problems that - in any other film - would bug me out, but in this film, I honestly didn't care about them. The small issues here and there were overshadowed greatly by the sum brilliance of the film.
What issues? First of all, the inconsistent tones in some scenes. You would expect that a film carrying such a grim premise would not be providing as much humour as this film does. Captain America delivers a serious address to the Avengers only for Rocket and Antman to respond with humorous remarks. I recall some moments where a very serious scene transitioned into a humorous one that completely disrespected what the previous scene had tried to establish. But like I said, a minor issue, mostly because the humour was restricted to the first act of the film.
And that brings me to my second issue, the first act. The first act had some incredible moments. Thanos getting his head chopped off was COMPLETELY unexpected and made for a truly icon scene. But after that, it went downhill for a bit. The pacing slowed down to the point the film felt sluggish. I remember in the cinema feeling as if I was pushing against a blockade in a river, trying to push it away so the river could continue running its course. It did not help that most of the scenes in the first act were revealed in the trailer so you felt as if you were rewatching instead of experiencing something new.
What else? There probably are a few issues here and there that others will pick out, but that's all for me.
Did these issues ruin the film? ABSOLUTELY NOT. The film was incredible. It's leagues above any MCU film. I am usually quite critical of MCU films (rating most of them as B-rated action films) but this was a great film. The last two acts were so utterly brilliant that they outweighed the first act. The execution was excellent and a testimony to the skills of the Russo brothers, each character was given their own moment to shine and develop, the plot served up many plot twists that diverted expectations, and God damn it, was it emotional.
There is literally no way you can not watch this film. Even if you're not an MCU fan. Just watch Civil War and Infinity War (that's all you need to fill you in on what's happening in Endgame), and then just watch it. Do it. It will provide you with a cinematic experience like no other.
P.S: Another minor issue I had was the scene where all the females united. I'm all for female representation, but it was so clearly forced that it added for a :/ moment during what was one of the best battle scenes I've ever witnessed in film.
