Saw it last night as part of an Iron Man Movie Marathon at my local Regal theater. I've been telling people that this movie could have used the subtitle, "Iron Man 3: The Miami Vice Comedy Christmas Special."
I didn't care for it. It's easily the weakest of the 3 and the script writing relied to heavily on narrative tropes that were weak excuses for the plot to evolve or an action sequence to happen. With so many great stories to lift from the Fraction and Ellis days, it's astonishing they couldn't have come up with something better. Shane Black relies too heavily on his Lethal Weapon past to make this movie entertaining; the movie seems to be one giant evolving joke. Its as if he wanted to make another Lethal Weapon movie and was forced to have some Iron Man stuff in it.
I think SW Episode 1 TPM might be a better movie than this one.
