Yeah I don't think I ever saw the endings of the these episodes. They would air on PBS at 11:30pm on Saturday and I would always fall asleep like 30 minutes into them 
I just saw "The Sea Devils", which I thought was very good. So far in my Pertwee marathon I'd saw "Terror of the Autons" and "Sea Devils" were definitely the best, with "The Daemons" coming up third.

I don't know: The Ambassadors of Death - a complex, multi-layered plot about the real political and social implications of first contact. What's not to love?
