I finally saw it maybe a year ago or so. It's pretty genuinely "out there", and the music is generally good too. It's definitely a better "film" than, say, Magical Mystery Tour, and that's coming from a huge Beatles fan. It's pretty clear that they said fuck it and basically included any and every single thing that popped in to their heads. Plus, Jack Nicholson was involved. Criterion put it out on blu-ray, so you might be able to rent it somewhere...
