OK popcorn movie
Movie is okay - definitely not dumb as Transformers, has decent action and effects, interesting somewhat convincing navy terminology and background (for those interested), and surprisingly high level of respect for other nations - story happens during the forgot-the-exact-name international Naval Games - and even for the aliens, I dare say. Story is childishly simple, but does not undermine the intelligence of the viewer as Transformers did - simply said, this is a popcorn movie just like Independence Day. Not so strong in character development, but equally entertaining. As for Rihanna, I have nothing against her, she can act, sure, but to be honest, it was hard to imagine that fragile girl as a tough marine. Anywhere else I believe she would be good - here the role just didn't fit her.
