The holy mountain is actually really good imo. I found el topo quite boring whereas with the holy mountain Jodorowsky had a big budget (via the beatles) so its a constant stream of crazy fantastical visually inventive random shit and is really fun.
I love all his movies with the exception of the Rainbow Thief, which is so terrible as to almost be good again, particularly the "Peter O'Toole swimming with a dog" sequence.
