The Message From Deep Space: just want to put my hat in the ring and say that even though I’m only in the 200s (out of what was it, 900 something?) and that’s apparently taken me 8 hours, I do not feel that this is slow or boring in any way. Occasionally I am a little like, ok ok, I get it, but only occasionally - very frequently even if the answer is obvious the transmission is adding more information, and anyway the diegetic explanation always makes sense - the aliens are trying to be as robust and precise as possible, to ensure understanding.
But mostly, I am electrified. The end of Act III just about blew what’s left of my hair off my head. Legitimate goosebumps.
