To begin: I was impressed by Infinity War and went in with high hopes. Specifically, the two things that I loved about Infinity War was (a) how well it worked the theme of "saving your other half vs. saving the other half of the universe", and (b) all the great character interaction moments that are only possible in a large cross-story movie like this.
(tumblr has deleted the post, but
here is a proto-version of what I wrote last year.)
As a result, I was disappointed on both of those counts.
