Finally got the game today, played through the first two stages. I like it a lot so far but I can see how it isn't for everyone. It feels like Buffy the Vampire Slayer + a Troma movie + No More Heroes with a Tales from the Crypt comic book style presentation to the menus and UI. Those are all things I really, really like so it works out well for me. I also dig the music. I <3 Joan Jett. And I think it's great when, in the middle of the metal soundtrack of the second stage, you activate the power up mode and Hey Mickey starts playing.
The jokes sometimes fall flat, and other times I find them pretty funny, so it's a bit of a mixed bag there. I see what they're doing with Juliet, trying to make her super girly but also a badass zombie hunter, but the way they communicate the girliness with super stereotypical lines like "I love shopping!" and "Does this make me look fat?" kind of stuff just feels lazy and makes her feel less like a character, but she also has personality and plenty of good lines to make up for those kinda cringe-worthy moments.
