Lack of good storyline.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

It’s not bad or unwatchable but despite the amplitude of the spectacle, the end result is underwhelming.

Exactly the movie you think it is, but not the movie you want it to be.
