Here's Ben Milot's description of the challenge:

It's time once again for the Letterboxd Season Challenge!For the uninitiated, the Letterboxd Season Challenge is a 33 week long challenge where the goal each week is to watch a previously unseen feature length film from a specified category. And though they are in chronological order, you are free to follow along or watch them in any order at your leisure. Start whenever, finish whenever! You are also welcome to watch multiple films per each week/theme if you so choose. You can find the weekly challenges by reading the notes of this list.The idea of this challenge is to push you to check out films you may not have otherwise, or to give you that little kick that's sometimes needed to watch a film you've been meaning to check out but just haven't yet.As always, I'm super glad to be hosting the Challenge and for the fourth year in a row! Might be hitting my term limits soon, but it's always fun crafting the Season and sharing it with you all! Make sure to post your list in the comments once you've created them. You are not beholden to your original selections. You can swap out or mix and match any films you want as long as they fit the categories. And if ever you find that you've seen all applicable films for a specific week, comment down below and I'll offer up an alternative.And don't forget to tag all lists and reviews with "letterboxd season challenge" and "lsc7"!
