I enjoyed it quite a bit. :) In a lot of ways, Love Hina really nails that "Romantic comedy with a touch of WTF?" feel that I want for Suburban Jungle, so I've been drawing a lot of inspiration from it. Naru and Tiffany would certainly get along well, that's for sure! The main difference is that, unlike Kietaro, Leonard can give it back to Tiff just as good as she can dish out to him.
We've still got the movies to get through ("Christmas Movie," "Spring Movie," and "Love Hina Again") ... it'll be interesting to see where things go. Amazon has mixed reviews, but the plot summaries suggest that the story is not quite over yet.
