Quite good! Really good pacing, plenty of complex human relationships and credible reactions. One of my favorite aspects of the first Fantastic Four movie was the bickering between the team members, it “rang true” to the characters as they were presented in the comics. That aspect rings true again here. Awesome ending! Great way to finish off the movie!
Someone asked me how Amazing Spider-man 2 (Andrew Garfield this year) compares to Spider-man (Tobey Maguire in 2002). I thought it was like comparing Superman II (Christopher Reeve in 1980) with Man of Steel (Henry Cavill in 2013) where, in both cases, the title character meets General Zod and company. In both cases, the two sets of movies are made with such different sensibilities and the pairs of lead characters are so unalike that the two sets of movies aren't really comparable.
Probably the biggest similarity between the Cavill Superman and the Garfield Spider-man where both of them dramatically contrast with their earlier versions was in the immense amount of property destruction that the later versions engage in. In both cases, Reeve and Maguire are sunnier, more cheerful characters than their later versions are.
