number one: cool storyline that breaks away from the mythology that is dominating the 9th season. sometimes an episode that is a departure from the mythology can be nice.
number two: great use of burt reynolds in this epi. never thought i'd see him in anything sci-fi related. just shows what a great and versitile actor he really is. even if its not his best role or work he still makes it look fun.
and the part with doggett noticing the 6 on the map, and when that 'genius' tells him the killer's description [wets bed, white, average build and looks]; doggett's response? "you've just summed up every serial killer the fbi has on file!"
