Really good start to an amazing series. It's even better the second time through with all of the witty dialogue and character build-up. You can see how they've grown from this point compared to the later series.
The show can be a little hard to pick up but just keep an open mind and observe what's happening between the characters and I'm sure you'll come to love them. Keep in mind they like to mess with each other quite a bit :) Be sure to expect some quirky behavior sometimes, but it's also not all fun and games as you'll see. Every so often shit will get real.
All in all, this show has a lot going on and it is a really amazing story continued through multiple arcs and smaller stories. The character interaction is so so fun.
