After rewatching the Keaton, Chase, Shemp, Besser and DeRita solos, one can appreciate how well most of the Stooges shorts were made. I found many of the solos interesting, but paled in comparison to the well timed execution of many of the Stooges' shorts. You get the feeling that (until the slashed budgets and remakes) more care went into their shorts than the others.
I own the Keaton disc set and only two titles merit rewatching IMO!
