I’d modify the question to specify that each life is presented as a unique and compelling motion picture, each between an hour and four hours in length, of the sort that would be likely to win either critical acclaim or box office success (or both) at some point in the late 20th to early 21st century - and that I get to watch them in an unending variety of well-staffed and enthusiastically-attended movie theaters, with interesting companions who I can discuss the movie with for as long as I want to afterwards, with endless credit to spend at the concessions, and with no bodily needs like discomfort or fatigue.
