So what's wrong with the film? Well, Reed Richards is blatantly too young; the character of Doctor Doom is mishandled in exactly the same way as the otherwise excellent 2005 film, portraying him as simply an arrogant scientist who may as well be American; and it does the bloody origin again, which is something I keep banging on about as something films should avoid as they're essentially just exposition and it's best just to skip to the action.
But what's truly unforgivable about the film, aside from the cast's utter lack of charisma, is that it utterly fails to do this. It's boring. Literally nothing exciting happens until the last ten minutes. It takes a lot to make a film about the Fantastic Four that's just dull, but this has managed to do it.
I suppose you could say that the film successfully conveys the horror of Ben Grimm's situation, and it's nice to substitute another dimension for cosmic rays, but this film has no other redeeming features. This is one to be watched only for the purpose of slagging it off in blogs, which is my way of trying to justify wasting my time on this dreck.
