'The Titan' was a big heap of tropes and big leaps we're just expected to gloss over. It was like The Island of Dr Moreau with shit writing and bad acting. And I'm not even going to talk about the military backgrounds they just throw onto the characters for no purpose.
Sam Worthington isn't in this to act much. In fact the only person that does much acting is the antagonist, Tom Wilkinson, and his character arch goes from wanting to save humanity to being some sort of mad scientist that tricked the world into paying for his experiments somehow with falsified research.
Save yourself some time, watch the trailer and pass on this one. Unless you just want some background noise that is. In that case The Titan does that just fine with some weird pseudo-science and a little bit of fun for the make up department.
2/7 would not recommend.
