I thought this was great.
Pascal was a lot more interesting as Reed than I expected, and gets my favorite line in the entire movie. But the film really belongs to Sue and Johnny. Vanessa Kirby flat out killed it, she was amazing. I thought it was intriguing that they essentially use Galactus as a metaphor for being a new parent, and facing something overwhelming and life changing that you can't really understand until you've done it.
I also though they did a really nice job with the Surfer. I liked the darker, more matte tone they used as opposed to the really burnished, shiny look from the first attempt. Galactus looked and sounded great, but was more a presence than a character here.
I think I liked Thunderbolts/New Avengers more overall, but that says less about the quality of this film than it does the quality of that one.
