I am never gonna look at this favorably. I cannot look beyond the obvious corporate reasons for this and the ethos behind the creative vision here. All I can do is hope the movie is entertaining on its own merits, but any hopes I had at enjoying this as much as the others I think is unlikely. The lead up isn't there, and this is clearly not done to make for the best story. I hope for the best, but I am expecting these to be my least favorite Avengers films. If they blow me away, great. Expect the worst, hope for the best.
Thanos had real anticipation before his first proper appearance cause they did a great job teasing him, making well regarded movies, and cresting an appetite for him. Then stuck the landing. You cannot replicate that by sticking RDJ in a different mask at the 11th hour
