The Wire - Season 5
I got carried away and watched all the way up to Ep 7 of the Wire (damn you internet leaks) and as such I now no longer remember which parts occured in which episodes. I must go back and watch them again so I can break each one apart and assess. But I won't do that until just before the final two episodes air.
I can say I really enjoyed Munch's cameo, that was ace. But I've enjoyed all of the cameos this season (characters from previous seasons). Fingers crossed that Bunny and Prez turn up, I've missed them both.
