Pantheon season 1 is being added to Netflix tomorrow, but season 2 is not (and might never be). Both seasons are on Prime Video but it is region-locked, though I’m not sure which regions it is available in.
Pantheon is a fantastic sci-fi show with really smart themes that has been completely screwed over by streaming services. The writing is incredible and contains some very intelligent satire and critiques of big tech corporations, and even dips its toes into geopolitics (not even kidding, the Israel-Palestine conflict becomes a plot point in season 2, and this was written prior to Oct. 7).
If you want to watch the series in its entirety then piracy is a must for the vast majority. Needless to say, I highly recommend watching.
Very much worth a watch, this show is pretty unique. It does complete its story arcs, so you will not get frustrated by that if that is your worry.
