At the moment, Haruhi's show; which ranks up there with Evangelion and Excel Saga in my top 3. Love Hina comes in second-to-last since I just finished the show proper and will watch the rest of the movies I bought very soon.
But before any of that, however, any day now I'll be adding Death and Rebirth and End of Evangelion to finish my initiation into EVA otakudom first. :Hvhappy: Priorities are just that after all...
