Is there any mainstream film with a lower IMDb rating?

The Gaul is also known as Druids.
The rottentomatoes score is only 15% of audience liked it (almost 2,500 ratings).

Btw, there was a thread some months ago in which I said that I have found that there are certain clues that a film will have a higher than average chance of being disappointing.

(1) written and directed by same person
(2) first-time director
(3) no theatrical release (made-for-television or released straight to DVD/VHS/streaming)
(4) more than two people credited for writing (excluding credit given to an original novel or story from which film was adapted)
(5) for US films, no recognizable actors other than maybe a few B-grade actors
(6) extremely low budget (as in Super-8 with chewing gum and duct tape)
(7) produced in a country that has had little to no internationally recognized film industry (eg Romania)

The Gaul was written and directed by the same person, had more than 2 people credited for writing, and apparently was filmed in Bulgaria.
