"Her" was actually very very good. All the shots were beautiful and it was slightly sci-fi-ish but not very far into the future, so most people can relate to it.
Probably my favorite movie of 2013.
"Gravity" was a very pretty movie and the effects were incredible, but the plot made absolutely no sense to anyone that actually looks at it. I would go into detail on why this is but it would contain some spoilers and you guys probably dont care anyway
