It was girl shit, so I ignored it first run.
On DVD it's pretty good.
But in the final days, after JJ tied everything off, packed up his shit, and got ready to go home (start making Alias) the network said "Something else fell through, so can we have another 6 episodes?"
Do you want to know how much this pissed off JJ Abrams?
TIMETRAVEL!
In the last 6 episodes, Felictiy goes back in time to the middle of season one and doesn't cut her hair and jumps time tracks completely by dumping the boy she wound up with and pursuing the boy she always should have done, but unfortunately Felecity quickly becomes Destiny's bitch as butterfly effects and knockons keep frakking with her sense of order and everything goes horribly wrong.
Whenever the character said "Break the space time continuum" I got a soul boner.
