So we've all done it; gone to the theatre, watched a movie and decided it was awful. I've done it more than a few times myself.
But recently I picked up Battleship (2012) at a second hand store because it was an absolute steal. Now I'd seen it in theatres back when it came out and wasn't overly impressed by it by any means.
So I popped it in my DVD player that night and gave it a watch- turns out the thing is not only more comical than I remember, but the action scenes are kinda awesome.
Sure, it has its many faults, like Rihanna's acting which is borderline painful - but if you put aside the bad, it's definitely possible to enjoy the movie.
I'm sure this is also the case for a lot of the movies out there, which are sitting on second hand shelves all over the place.
Except for Soul Survivors. I've seen that a couple times and it's absolute crap no matter how hard you try.
