I thought the idea of releasing Green Lantern in December was unusual, at first. Not just because it seems like a total summer blockbuster, but because the script itself is very... summery. Coast City, sun-drenched airfields, etc.
But the more I've thought about it, the more I've decided I like the release date. It's the week before Christmas. Plenty of families are out doing their shopping, and looking for a movie to see once they're done. And too often we see some mindless holiday-themed rubbish doing big bucks just because it's showing that week before Christmas, when nothing else is. So it'd be cool seeing a worthy film in that slot again.
