I just saw Otherland (w. Chris Bush, dir. Ann Yee) at the Almeida Theatre and I was a WRECK afterwards. Such a powerful portrayal of the struggles of the two lead women — one navigating coming out as trans to her wife, her family, and the world, and the other with divorcing her, having her own identity crisis, and struggling with having children — and so many bold decisions made in the storytelling and staging (particularly in the second act)!
I really don't want to spoil anything so all I'll say is that the set, despite being largely a plain stage, has a specific piece that will probably be one of the most memorable bits of theatre I've ever seen.
If you're in London do see if you can get tickets before it ends in March, although beware as it is quite heavy at times. I managed to get a very cheap under 25 ticket but I believe these are all sold out. You could try queueing for the Free performance night which I believe opens soon!
