Of all 2013 films I saw I rank White House Down as the worst.
Even it can be a fun movie to get lost in for a while.
What knocked it down even further for me was the gratuitous little girl life threatening/putting a gun to a little girl's head repeatedly.
5/10
I forgot I ranked Oz the Great and Powerful below it, but also 5/10.
Watching it on DISH in Full Screen didn't help either.
RIPD only avoided 5 because I thought the Ryan Reynolds death/ascending in the sky scene was pretty good.
I enjoyed Oblivion.
I have forgotten much of Gangster Squad, but I do know one of the biggest sequences/set pieces had to be cut because of the theater shooting. So I have to wonder how much that hurt the film.
**update**
Just saw The Internship. Man, that was a stinker. I think it goes with the 5/10's and that may be generous.
