Okay, that answers some questions. Yay knees! He actually looks to have better leg articulation than the Vipers and the RSX. Love the rotatable leg detail; very nice touch there. It's not my favorite Alt, but he is really starting to grow on me. Besides, it's hard to judge a Transformer until I'm actually holding it in my hands. I expected Alt Prowl to be pretty crappy, but I ended up loving the little guy. Optimus might be another one that I'll really have to fiddle with in order to fully appreciate.
