Agree he looks totally wrong as Reed Richards. It seems like he is part of a Disney stable of actors and they just decided to pound the square peg into that particular round hole.
The casting done on the 2005 Fantastic Four movie was very good in my opinion, Ioan Gruffudd as Mr. Fantastic. Jessica Alba wasn't a perfect physical match to Sue Richards, but she did a nice job in that role.
The little dialogue snippes I've heard and the trailer on this year's movie seemed pretty lame. Disney has shown an impressive ability to completely misuse any property. I'll wait and see what you think of it.
