A lot of the Marvel movies made over the past few years have been quite well done and well worth watching. A few have been duds. This one is somewhere in between. I found the concept to be patently absurd (his ability to transform from full size to ant size in a fraction of a second, and then back again, over and over). This was quite disappointing as many of the other films have quite successfully come up with newer and better explanations and origins for many of the super powers. Paul Rudd was good, as usual, though. The story was so-so.
