I'd say that the "with friend part" depends on your own personality: if you like watching movies on TV "with friends" then you probably will like to go to the movies with friends.

If you don't really feel the need to have people around when watching a movie (or to chat about it afterwards with somebody that watched it along with you), you should still go to the cinema for one of those more grandiose films (the recent Avatar is a good example) - you can't easilly reproduce the massive screen and proper sound system in a large room experience at home.

One of my best movie experiences was watching the Star Wars: Rogue One movie in the cinema because I was lucky and there were only 7 people in the whole room (so I had none of the possible problems in the cinema experience, such as having a tall person right in front of you obstructing your view to the screen or there being people in the room constantly chatting) and that movie really had the abundance of grandiose scenes that massivelly gain from being on the big screen and having proper sound capable of the kind of thundering bass that physically rumbles your seat.
