Update: I was unfortunately not aware of Shamus Young's severe criticism of Fallout 3 available here to link in the original piece and I regret that. It dovetails rather nicely with what I've written and it's much better executed than my piece. I strongly recommend anyone...
The Good: Good quality comics, great for promoting the series
The Bad: Comics have messy art, no voice acting, not "interactive" at all
I was surprised how little there was in SHE. While the game is hardly interactive (just "interactive" menus) the game does sport some good media to keep you busy for a few hours. While the "game" only has two full length comics (and they're damn good) the art is really messy and there is no voice acting. There are trailers for every Silent Hill media type you can think of (except Origins) and interviews with the music creator and director of the movie and that's about it. The music during the comics creates a great atmosphere and this is a good purchase for maybe $10 or so but nothing more. I only recommend this to die hard SH fans.
