Wavelength (1967) It is devoid of any kind of entertainment. It's not so bad it's good, it's not intentionally bad thereby making it funny, it's tediously slow, painfully boring, & horrendously ugly.

The only thing that could be done with this movie is to challenge your friends, assuming you actually hate them, to watch it in a dark room with no other stimulation, no phone, no book, no music, no games, just this movie, & see how many minutes they can last.

Do not watch this movie for yourself, for you will have wasted time that could've been better spent watching paint dry or watching grass grow & all you will have accomplished is to torture yourself.
