Kid loved it, and I loved that he loved it.
The script flows like it was written by a well intentioned tv writer. And though it is entirely cgi driven, those efforts are fairly meh.
Having said that, it was a fun movie and my son LOVED it. He and a few other kids clapped multiple times throughout the movie. Those are the only opinions that I am truly concerned with. If this movie was anything other than a Marvel project most would likely consider it a solid outting. But . . .
