Ah, good old "To-LOVE-Ru", how I love you. Yes I will admit this is a guilty pleasure of mine, but lately I'm thinking of not calling it a guilty pleasure since I don't usually like anime/manga like this anyway.
Yes, it is another rip-off of "Urusei Yatsura", it is another cliche-ridden ecchi/harem series, but along with "Tenchi" this is probably the only one I've cared about. For one thing the visuals are nothing new, but I appreciate how unlike a lot of other series out there the characters actually look like teenagers. One of the things I make fun of with "Bleach" is that while the characters are supposed to be 15 they look more like 18 or 19. And I like all the silly non-detailed character designs like the old teacher and the stray dog. More importantly the characters are actually pretty appealing. Yuuki is another lame, weak underdog guy who's too shy around girls, but he still shows genuine moments of determination and good intention. Lala is another ditzy shameless girl with a big bust, but she's not stupid and also has good intention. It is all about the fanservice like many other series of it's kind, but it's not just about the pantyshots and awkward situations, the ecchi moments are mostly pretty funny despite a mostly lacking originality thanks to slapstick and how they manage to keep things lighthearted despite how far they can go with the suggestive (and obvious) themes. There's more I like about it but I don't want to get into it now, but for now I'll say the only thing holding this series back is that it's still another rip-off of "Urusei Yatsura" that depends on fanservice.
One thing I'm interested in is why the manga hasn't been picked up by VIZ Media yet. If you look at VIZ's track record they'll come out with a manga the year the anime version comes out in Japan, but we haven't anything about "To-LOVE-Ru". Is it just that the release schedule for VIZ is filled up at the moment? Is the content too risque even for Shonen Jump Advanced? Or maybe there are plans and we just haven't heard anything yet? Who knows.
