Yeah, the problem with Day After Tomorrow was it's seen as a "message" film -- and it was. The whole green, environmental theme. No one likes heavy-handed message films.
Independence Day still remains one of the best "cheesy" extravaganzas of all times. Roland Emmerich definitely is a master of this genre. And I'm glad he's back to do his thing.
I'm sure, though, he's going to sneak some "messages" in there but hopefully it would be more subtle and ironic this time. I love, for example, how the Vatican crumbles, killing all the folks holding vigils. It's totally un-PC (probably controversial, too) and ironic. But in the context (it's, after all, about a Mayan prediction), you have to find some humor in that.
