So I've spent about two weeks on watching season 1 & 2 of Dexter on my computer via Netflix but the other two seasons are on disc only, and with each season having 3 discs, I won't be able to get through all of the discs before the Season 5 premiere on the 26th. I have no idea what goes on in season 3 and I have basic understanding of Season 4 (Trinity Killer, Rita dies, yadayada). So, would I be alright to just go ahead and watch Season 5?
