I'm a big fan of the MCU. This movie is a step in the direction of cast introduction and character building. Marvel has opened the door for "yet another" sequel-rich franchise. The script was in need of some trimming to sew it up better, with a few scenes long in duration.
The action scenes were technically exciting and vivid while viewed immersed in an AMC Dolby Cinema Theater. The Dolby sound was sweet science to my ears.
Overall, it's sure to drive up the stock in AMC and Marvel.
