Iron Metropolitan is finished and I thought the arc was pretty decent. It ended up feeling a bit like filler in anticipation for Rings of the Mandarin. I didn't like Red Peril being so viciously injured at the end of the arc. I thought she had great potential as an enemy/erstwhile ally of Tony & Arno. The reveal of the villain as Malekith was a bit disappointing. I was hoping it'd be a new enemy for Tony or an Iron Man we haven't seen in a while.
All in all I would probably give it around 3/5 stars. Joe Bennett's art throughout was outstanding.
