It was fun while it lasted.
That site should have all the ep's, but sometimes stuff get's cut off, it shouldn't be overly hard to find the ones it might be missing.
With the last ep up, that's all of season one and two.
And we have yet to confirm whether the show is cancelled or continued or not.
But given Loeb's... Loebness, I wouldn't bet on a good outcome here.
Suckers bet.
