I recently binge watched the first 3. 3 was a bit of a mess think I'm hoping 4 will make more sense though with some of the returning characters ep 1 I'm already confused lol
I Loved season 1 and season 2 was good but confusing lol....I haven't been able to watch 3 or 4 as I don't have that channel on the virgin box now :( so I hope it appears on repeat on one of the other channels some time (season 1,2 was repeated on sci-fi channel)
