I loved most cult classics I've come across. If not for the fact that they were terribly awesome, then because they were so hard to find at the time that getting them made watching them worth it.
Cult classic movies like Planet 9 from OuterSpace, 2001 Space Odessy, and Lost Skeleton of Cadavra were freaking terrible to the point of being hilarious a decade or two ago, but most people getting into them these days weren't living in the era they were meant for long enough to understand where the movies are coming from.
Similarly, FF7 (which is not a cult classic) is hated mostly due to the fact that many people who play it now weren't around or sanely able when the game first came out for the PS1. It was insane how popular it was. It brought RPGing to a new dimension with such a deep plot with many interesting hardcore characters and many people bought their PS1 for that game. I love it to this day, but only because I played it when it first came out. A 'newbie' playing it today with no recollection of the past may be too guppied by the graphics or differences of today's culture to fully appreciate it. It was so awesome that people found it cool to hate it when it was re-released as a 'best seller' five some years after the fact. Now people hate it either for no reason (ie, it's 'cool' to simply hate it, even if it's never been played), or because they grew up in a different age and place.
Back to the thread topic, I love most cult classics. I loved Shadow of the Collosus, Okami, the original GTA (and GTA:london), Lufia 1 and 2, Valkyrie Profile, Vagrant Story, Rhapsody: a Musical Adventure for the PS1 (which was insanely hard to find back then), Way of the Samurai, Day of the Tentacle, 7th Guest and 11th Hour, Return to Zork (for crying out loud!), and the such. What's up with all the hate? So much pessimism.
So... Nope, don't think I hate any. Fact, even games like Spore (and I don't believe that quite reaches cult classic yet) has its charms, even if everyone was insanely disappointed by its release.
