Sex ought to be funnier than this

It had a lot going for it. A funny idea, a mellow Cuban vibe and potential. Unfortunately, the jokes won't ignite and many scenes just fall flat. Also contains a painfully misguided good-will-hunting-ish speech scene that isn't even trying to be funny.

Another movie with Liam Neeson, definitely not one of his best

I am still wondering what the writers were thinking, as well as Liam Neeson reading the script. Watching a goldfish in a fish tank for 114 minutes must be more exciting than this...

Bad - but sympathetic and unpretentious

You B-movie you! With your continuous bombastic music blasting over shaky camera shots of people constantly jumping in and out a car! But it's sort of all right, it does what it can. Effects are sufficient. Fair game.

Derailed

After a reasonable start, it derails in cheesy teenage love stories, unexciting screenplay, annoying army-squads comprising of teenagers and emo's, and sloppy movie making with aliens that conveniently look just like humans.

Awesomeness that left me cold

Such a potential premise, such a big budget, yet still so uninteresting and shallow. I thought only the finale back on earth was somewhat badass. The movie seems to look a lot like the game it was based upon, so perhaps fans will get more out of it.

Overdone

They managed to get a whole bunch a A-list actors giving all they got. But it feels overacted, over dramatized and forced down your throat. The clips during the end scroll demonstrate how veterans ACTUALLY talk. A noble cause for sure, but unnecessarily heavy-handed. Boring, even.

Too tedious and uneventful

The story is familiar, but one that always seems open for a new interpretation, and it's a story that can work just fine with limited budget like this movie. Unfortunate, this one failed. It is mostly tedious, slow and uneventful, and lacks the philosophical or technological wit to make it deep.

Mission failed: please try again

What happened? They got great looking props, effects, a spot-on color palette, an exciting Halo playground, and even the warthog. Yet all they came up with are close-ups of whining and insubordinate teenagers, and a minimal story that's still going nowhere.

Too complicated, not enough magic

It kept some of the magic of the original, but what it kept mostly is endless incomprehensible techno/politics that I could not stay focused on. It's not bad looking, but most of the art of the first movie is no longer here.

Not the killer pulp I hoped for

A film with a good chance of being so outrageously bad and incorrect that it becomes secretly enjoyable, but alas it had too little good ideas or energy for that. It's all quite lifeless. All the zombies walking around with their pants on their ankles earned it a bonus point though.
