It looks like "more of the same, except bigger". In the case of Independence Day, that's about all one needs from a sequel.

I'm not going to anticipate it with bated breath, but I'll most likely see it and almost certainly enjoy it as a couple of hours of dumb, escapist fun.

The original movie's going to be 20 years old when the sequel comes out. Holy crap. Mae Whitman, who played President Whitman's young daughter Patricia (as well as Yuffie in Kingdom Hearts, coincidentally) is 27 now. For some reason she's not reprising her role in Resurgence, though; the role's gone to someone five years younger instead.
