The bad, oh the bad, well the first bad is a good as well. There is a lot of panties, in fact so much so that it gets boring. Not to mention it seems to be dirty, after all they wear the exact same... EVERYTHING. Seriously, there you could make the show some what arousing by changing the kind of panties that the characters wear. But nope they decided that they do not need to change their underwear. So it is kind of foul, and boring after a while.
Then there is the reliance on the female lead character, gets boring after a while. I mean it is at least amusing when you know that both sides could have an equal time winning or losing. But when there is the trigger that shows that everyone else is going to get an ass whipping. That gets old, god if only they had perfected digital fast forward. You could skip the generic 20 seconds to 1.5 minutes it takes to end the fight and get the the fucking resolution.
And as always there is the awkward male female relationship. Seriously, this gets old. Especially when the characters stare at each other and spend about a minute saying each others name. Then the blush and there is music and then it is broken up. Generally with a nice face full of boobs... because the females seem to only be able to put their boobs in the males face... yeah.
