Doug Dillaman’s review published on Letterboxd :
Now that the review embargo has broken, I can say: I liked it. All the endless deck chair shuffling of previous movies has led to something with stakes and consequences that feel real. Battle scenes mostly pro forma as always, but a lot of nice touches and character dynamics. I don't want to oversell it (especially to skeptics who probably shouldn't bother) but I had my "infinite bore" hackstamp picked out in advance and was actually never bored (which has not been the case in the other two AVENGERS or CIVIL WAR).
MVP: the writing of Thanos.
