I loved the movies too, up until Afterlife. It wasn't terrible but it wasn't good either. It was very slow-paced and all that slow motion made it, for me, tedious to watch. I didn't really care that the movies didn't follow the games. They were, as you said, fun to watch. Afterlife was not.
I, too, thought the false Sony commercial was clever. It reminded me of the teaser for the first movie that portrayed the Umbrella Corporation as a cosmetics company.
