I have grown cautiously optimistic for the new Fantastic Four film. I personally think the F4 look great but I'm still holding out reservation on Doom. Toby Kebbell is a great actor so I think he can deliver so long as the script allows for it. Obviously, I want nothing more than for Marvel to bring Doom and co home, but since that's unlikely, I just want a good movie regardless of film rights.
I'm not the biggest fan of the metal skin either, but it's true to Ultimate Doom so I will give Fox credit where it's due. And it's nice to see the tunic/hood/cape combo. At this rate, I'm willing to accept some aesthetic grievances in return for proper characterization. In the grand scheme of things, I find that to be far more important than the look so long as his appearance isn't too butchered.
