For the above!
The general definition of a cult movie is something that didn't do particularly well at release, but which has developed a devoted fanbase over time who love it despite it's flaws, and enjoy rewatching it.
E.g. Rocky Horror, The Room, Withnail and I, Tron, Bladerunner, Evil Dead, Clerks, Blues Brothers, Monty Python (Holy Grail/Life of Brian), Big Lewbowski.
If you watch something once, and have no desire to either re-view or discuss it, then it's not a cult movie, it's just crap ;)
