-- i think H3 is great and is the best Halloween sequel to date--
That is the root of the problem. "Halloween" in horror genre terms are the Mike Myers movies. To call this one a "sequel" is stretching the definition of the word beyond its limits. It has nothing whatsoever to do with "Halloween". Therefore, it is, in the very least, a very strange "sequel".
Regardless, it's just not that good, imho. Half of it has possiblities ina Twilight Zone kind of way, but the latter moments in the film are lame.
