I just hope Thor can ride that momentum as well despite the ill received Mandarin twist.
Iron Man 3 being the "weakest" Marvel movie is HIGHLY debatable. It got good critical reviews, the GA really liked it, and it make tons of money, it's a success in every sense of the word that matters. I hear more people point to IM 2, or TIH, or even Thor as being the weakest Marvel movie than IM 3.
