I overhyped this and as a result the movie was a let down. It still had value and I'm still glad I went, but it felt like an avoidable side quest.
It was boring and slow. Children in the audience were antsy. Several parent/kid pairs walked out.
It was more Star Trek than Avengers. I didn't expect this to be Avengers, but I somehow felt cheated that it wasn't. It was a great dip in the slope of Marvel movie entertainment.
The after credit short was BS.
I will give this some time before seeing it again. I really want it to be good. I doubt I will see it again in theaters however.
