The Conversation - Great. My interpretation of a bunch of it changed on this second viewing.
Rumble Fish - also by Coppola. Couldn't get into it.
What Ever Happened to Baby Jane? - a surprisingly decent psychological thriller given the era. Throwing more fuel onto the real-life feud that is part of the movie's appeal, I'll just say that Bette Davis is awesome in it.
Donnie Darko - Hadn't seen this in ~13 years. My impression of it in the subsequent years (expressed here by me and others) was that it's one of those films that throws a little bit of pseudo-science, time travel, plot confusion, some philosophy, some fun, and some tragic teen drama together in such a way to appeal especially to high school/college viewers and less experienced filmgoers, who think it's the second coming because they've never engaged with anything other than superhero films, Pixar, Harry Potter, and video games.
It was even worse than I expected. Strong influence it would seem from then-recent films like American Beauty and Magnolia, taking mostly surface-level elements and trying to fit them onto something new.
I was hoping it would at least be a little bit fun and interesting and that I would roll my eyes just a bit at its attempts at being heady. But nope, it wasn't even at that level. I was eye-rolling for it to be over.
Prisoners - Solid kidnapping thriller with unexpected and disturbing twists. It mostly lets you off the hook though.
