If you use Netflix primarily to watch TV shows, you may want to binge as much of it as you can right now.

Netflix released the list of titles coming to and leaving the service next month, and while Polygon will compile those lists as we do every month, we thought it was especially important to point this out.

Buffy the Vampire Slayer, Angel, Arrested Development, Firefly, Ally McBeal, The X-Files, Roswell and House are the bigger, more notable shows being tossed aside in April. Every single season from each show will no longer be available to stream, with the exception of Arrested Development’s fourth season, which will remain due to it being a Netflix exclusive.

Netflix hasn’t said why its getting rid of the shows, which mostly belong to Fox, but Polygon has reached out for comment. Netflix’s chief of content, Ted Sarandos, has previously said the company’s goal is to have at least 50 percent of the content on the service be exclusive to Netflix. The company has invested more than $6 billion into developing new series and licensing adored properties — like Arrested Development — but it appears other shows may disappear as a result.

Each of the aforementioned series will no longer be available to stream as of April 1. A full list of what’s coming to and leaving Netflix, Hulu, Amazon and HBO Now will be compiled and published on Polygon as well.
