I can't believe I've voluntarily subjected myself to this movie twice now.
I was tricked into doing it because I thought if I watched the new blu-ray release, I'd finally see why so many people praise the cinematography.
Windows was shot exclusively in the absolute beigest section of 1979, already a very beige era. The director knows how to place lights, but except for the silhouette shot featured on the poster, I don't see any knack for composition here.
It's technically a homophobic movie, in the same way that it's technically a thriller. The intent is there, but it thankfully never actually articulates the horrendous ideas about the psychology of gay people that obviously inspired it. The stalker spares us any awkward paraphrases of outdated DSM entries by silently grimacing through all her therapy sessions.
So it's a lesbian panic movie, but it's not even very useful as a historical lesson on The Bad Old Days.
