Aaah, see, here I am lucky (or perhaps unlucky). All I know of JJ Abrams previous works is the first two seasons of Alias which were awesome (IRINA DEREVKO), and the new Star Trek movie. So while I know and believe others who say that he inevitably screws up the ends of his shows, I haven't yet had the emotional devastation that goes hand in hand with that.

There are two other executive producers credited in the titles though, so perhaps they will mitigate the Abrams Factor? *ponders...*
