As to Johnny flaming out, I noticed it happened when he mentioned saving Sue and Reed. Maybe this is psychological?
Its been a long time since Ben got a victory one on one against Doom. I don't think Johnny ever has and I would not mind seeing it happen sometime.
Johnny's cosmic dysfunction is the only thing that bothered me. I hope it isn't psychological. That would be lame. But this is still lame since he had a similar dysfunction in final FF series. I hope they finish this angle sooner rather than later. Still liked it, but this part not so much. Johnny fizzling out in battle with the extinguishment sound "fwish" was a bit disappointing. Not sure what Marvel is going for here.
