HBO MAX, the STAIRCASE, kept me up way too late last night, but so worth it

The STAIRCASE on HBO MAX starring Colin Firth and Toni Coletti made me stay up WAY, WAY too late. I didn’t finish it and hope I can find my way back to it. I have the most expensive TV package that is supposed to include this and that, but you have to sign in on each separately, and finding things is a bummer.
