This Love Hina dvd box is well worth the expense: 24 episodes on 6 dvds with 2 mini documentaries among the extras (an interview with the director of the series and a glimpse at the making of the english audio dub). The adventures of Motoko, Shinobu, Kaolla, Mitsune, Haruka, Mutsumi and especially the relationship between Naru and Keitaro (which becomes more and more complex) is very entertaining. Even though lots of cliches show up (like being cought at the wrong moment on many occasions) it's been done with a humorous twist. There are also deeper and moving moments and sometimes even flashes of symbolism, which give the series that extra dimension. The excellent musical score and the various songs (like the moving ballad "Yakusoku") also contribute substancially.
Some scenes may not be suitable for very young children (there are some sexual references and a few "scary" moments); that is why the series is rated age 12 and up. However, this should not keep you from watching it, because all is brought with light-heartedness and it's really fun to watch!
