I watched it on Saturday night in a theater that was about 75% full. I loved the first Avengers and typically enjoy the other installments of the Marvelverse (Captain America, Iron Man, Thor, etc..). While I enjoyed this movie for the action sequences and the banter, I think the novelty has worn off and the story was a little "meh."
Here is what I liked:
1. Action was top notch
2. Robert Downey Jr. He's great at being Iron Man/Tony Stark
3. Having multiple stars in one story is still cool
Here is what I did not like:
1. The villian(s)
2. The resolution made very little sense
3. I am unsure where this fits in with the broader story and if it is even necessary
I think the ticket is worth the price of admission and I hope the next one is can repeat the level of the first one.
