The only trouble with these practically arbitrary lists is that they aren't actually plots. Tragedy is a "plot?" ("Okay, so tell me the plot of the new movie." "Okay, are you ready? Here it is -- tragedy!") And "the quest" and "voyage and return" sound suspiciously like the same thing. Can't you slay a monster while on a quest? Or a voyage?Why can't they come up with something new? I'm really sick of all those remakes. If this trend continues, then we will never get anything original ever again ... just the same old characters and stories recycled over and over again.
There are only seven plots:

David Gerrold, in his writers' workshops, argues there are only three:
Man vs Nature
Man vs Man (or Woman)
Man vs Himself.
Joseph Campbell argued, convincingly IMO, that there is only one hero plot.
