The ones I've seen (including the Further Viewing list) are indubitably good; the ones I've heard of are likely as good; and the ones I don't know seem intriguing.

You're likely to have missed Window Licker; it's a love-or-hate film; either way, it's not likely to resemble anything else you've seen. One of my favorite films of this century.
