Definitely watch after Seasons 1 and 2, but only if you're ready for an intense ride into madness and despair. Gone are the side characters that made the TV series so quirky and soap operatic, and what's left is a study of a very troubled young woman in the days leading up to her horrific death. You'll get some answers, but the main reason to watch is that it takes a storyline that was rooted in fantasy horror in the show and grounds it in reality, showing the torment abuse victims live through and giving some catharsis to this heavy subject matter. You will feel sad and unclean, but that's kind of the point. Powerful, moving, and important.
