I really enjoyed part 2. While the battle with VS might be a "stretch", let's not forget, this is science FICTION. I'll always find it amusing - with Buffy the Vampire Slayer, for example - how people will point out one part of one episode that wasn't real. You're watching a show about hot teen chicks killing vampires! Get a grip and enjoy it! Suspension of disbelief is necessary for most shows, and frankly, part of the fun.
