Cheesiest sci-fi movie in recent years???

Yeah, the trailer looks pretty tongue in cheek. Is that a Sarah Palin presidency? FYI, Valhalla (as in "See you in Valhalla...") is the mythical pergetory/heaven of Norsemen and was rumored the name of an Antarctic Nazi sub base at the end of WW2 as many U-boats were unaccounted for after the Axis defeat..as well as the entire German wealth in gold, probably ended up in Argentina with the rest of the high ranking Nazis that escaped at the closeing days aboard large subs.
