Saw three today...
Non-Stop: 5/10 - Pretty damn stupid really. Almost entertaining in a mindless way, but not quite.
Stalingrad: 3/10 - Aside from some decent looking shots, this was terrible. The story is gibberish really, and "focuses" on a group of guys and a girl that we're told just suddenly care for each other, but are given no reason to believe it, and no reason to care about what happens to them. And the bookend scenes dealing with post tsunami Japan are just silly.
Anchorman 2 (Extended R rated version) - 3/10. I wasn't a fan of the first, but didn't hate it, but this was awful. I don't know how it compares to the pg-13 version as I didn't see it, but this was just dumb and unfunny with very few exceptions.
