I won't spoil the movie....

Endgame is terribly paced with actions that exist only to further the plot. Most character development is told to the audience instead of experienced. The movie breaks its own stated rules and character scaling makes no sense.

If you turn off your brain and stop asking questions of what is transpiring on screen, then yes you will enjoy the movie.

But if you ask even one question, you will become terribly frustrated and taken out of the movie. A film, no matter how fanciful, should suspend disbelief speaking to either real world logic or the logic it establishes in its own narrative. There is none of that, characters survive and perform actions only for spectacle and because it serves the whims of the writer not the story.

Fans frankly deserve better.
