It’s short, the movies are long and can’t be skipped, and the difficulty takes a dive at the end of the second hour. These are reasons to avoid a game. At the same time I love Onimusha, and Genji is essentially that game with a new name and face.
If you're a fan of flashy cut-'em-up action and Japanese mythology, you'll be glad to know that Genji doesn't stray from that path. Unfortunately, that path is a short one, and it ends just as soon as things really start to get interesting.
