So bad u gotta see it (to figure out how not good it was)

I won't bother regurgitating the plot, because the movie didn't seriously try to have one. It had an idea for a plot, but... well, read the reviews in the comment section.

This is going to be an analogy of how not good REINCARNATION OF ISABEL played.

It was as if... the producers had arranged a train wreck killing the entire cast and crew (including Renato Polselli) on their way home from location to collect on a life insurance scam. The wreck also destroyed all copies of the finished script but spared 90% of the exposed negatives. Not satisfied with just the insurance money, the producers then hired an undergrad film student to edit the footage into a releasable film by the end of spring break. With neither a script nor a budget, the student calls his girlfriend at the college radio station to borrow a few albums nobody at the station will notice missing and then join him at the editing studio. The two then spend the next week cutting the film and dubbing in the music and dialogue by themselves. Finishing just in time, they suddenly realize that one missing can of film rolled behind the refrigerator and was ruined before they could make use of it.

Thus, we are left with a finished product that is haphazardly structured, inappropriately scored, and buffoonishly scripted. We have a scene in which a doctor character is molesting his patient in one room while simultaneously applying a vampire bite to a different woman in a completely different room. SIMULTANEOUSLY, dude! We have a virgin-raping 3-way scored to ragtime harpsichord. We get a Donald Pleasance impersonator thrown into a snakepit with only TWO snakes in it and one is already DEAD. Even at the denouement when Laureen runs down the stairs, she's barefoot, but once outside she's wearing bedroom slippers. WTF, was she keeping them by the front door?
