Hi,
Great news for "Southland"!

Really enjoying Season 3 on More4 at the moment.
Seasons 1 and 2 are available on UK DVD, from any half-decent retailer, but the set is quite pricey - about £25 to £30 I think. (The reasons it contains both of the first two seasons together, is because they were so short - Season 1 ran for 7 episode, and Season 2 for just 6.)
Season 1 will finish on Channel 4 tonight, and if you didn't know it was being shown, that's because it's being shown for the first time on C4 at the wonderful time of 3am on Friday mornings, where they can then tell viewers that they won't bother showing further seasons due to "low ratings"!

So don't expect to see Season 2 anytime soon on C4!

Good job if you caught it on More4, earlier this year, where it played back-to-back with Season 1.
No news on a Season 3 DVD release date yet, but hopefully it will be in the middle of next year at some point.
