Pleasant people doing pleasant things and there's not much drama and you just kind of feel lovely about the world.
Note: gentle isn't the same as uplifting or heartwarming (sorry, WE ARE THE BEST! fans). It isn't the same as "quietly understated and heartbreaking" (sorry, YI YI and PARIS TEXAS fans). But feel free to go start those lists! Basically I started this one to find more films like ALAMAR, so if you've seen that, would love suggestions.
