Oh, but! Thomas treated me to Iron Man today. The movie was Awesome. And I even remembered to wait for the end of the credits.
However, the PG-13 was rather obvious about the time the dramatic tension got out of hand and Thomas was willing to sit in Mommy's lap for the last ~half hour.
My one and only quibble would have been the use of a cliche I hoped they were going to subvert. Alas, a vague memory from the few Iron Man comics I read tells me it was likely a CANON cliche and impossible to avoid. Not the movie makers' fault.
