Pretty sure I attempted this in 2019 and failed, then didn't bother in 2020 lol. I don't really expect to succeed this year, either (in my experience, the instant I "plan" to watch something I lose interest in it), but I enjoy making lists so much that I've decided to play along for at least a little while.
Each week, I aim to watch a previously unseen film from a specified category. The only rule I'm making for myself is that the movie has to be free to stream (I pay for too many streaming services to spend money on individuals films!). As streaming rights change month to month, this list will almost certainly be revised a few times.
Here's a link to the original list by Letterboxd user Benjamn Milot.
