In case you didn't notice make sure to check out my post in the dl rules section. I'm sure you already saw it since you were online when I made the original post but I figured I'd mention it.
School Rumble starts out kinda lame, but the girls keep you interested enough to keep watching until it gets really good about half way through the first season. After that it ends up being really fucking good. Quite funny too. I'm watching SR: Second Semester because I ended up enjoying the first season so much... and because I need more Yakumo and Eri...
Check out my review on the first season; it may convince you to watch it. When I finish the second season I'm gonna write a review on it too.
