Yes, yes, and yes!
Iron Man looks pure awesomeness. At least they put the Black Sabbath song in there!
The only thing that is worrying me is that Mr. Ford wont be able to pull off all the old stunts. (Which he may be able to do to some extent)
To much language? Pffft. That movie had hardly any if you compare it to some of the other movies recently released.
The plot had its bad points every now and then, but the main theing people look for in that movie is giant transforming robots that kick the snot out of each other.
The movie does look like it will be awesome. When I first watched it the girl in the car screaming "Hold on!" looked eerily similar to Ripley from the "Aliens" movies.
