Some titles are listed twice, particularly where there are noticeable differences between the two versions. In at least one case, though, one of the differences is in name, so it is less than obvious that "Leon" and "The Professional" are different cuts of the same movie. Likewise, movies where I have english and, say, japanese releases of the same movie will not necessarily show up together, so it might again be not so obvious that "Majo no Takkyuubin" and "Kiki's Delivery Service" are the same (though it might not be such a stretch to realize that Porco Rosso and Kurenai no Buta are identical).
It should also not necessarily be assumed that, because a title is listed, I like it. Although that's certainly the case for the vast majority (and, I believe, every title listed more than once), there are titles I bought, unwatched, and later regretted buying. It is also true that there are, sadly, several titles I have not yet watched.
