I didn't have a problem with Whedon directing... until I found out he would be rewriting the script!
As much as I love Whedon's work, he will be the death of this movie. His style of writing (especially his dialogue!) just has no place in an Avenger's movie.
I hope Whedon doesn't make all of the male characters effeminate like in everything else he's ever done. Angel, Spike, Wesley, Xander, Wash, Andrew? All act so effeminate that I sometimes wonder if they are supposed to be men or not.
The last thing I want is for Steve, Tony, and the rest of the guys to get this same treatment..
