I caught the second half of 28 Weeks Later tonight, but the last movie I watched in its entirety was Ex Machina. It's a little slow paced but quite good overall.
'All I Want for Christmas' because my retired dad is equal mixes of adorable and annoying because he friggin' loves Christmas films because they're so predicable and happy, and they're already starting to show Christmas films on TV.
The film was predictable, terribly-written, and badly acted. He loved it.
