if they'd wrapped things up in season 4 (spoilers)
While I still enjoyed Season 5, I know it gets a lot of flak from fans for the unrealistic fake serial killer storyline, the lack of depth to the newspaper staff, Omar's "spiderman" escape etc.
I've also got to say on further viewings that while the first half of season 4 is amazing, I'm not convinced by the way it finished. Naymond being adopted by Colvin felt like a deus ex machina, likewise Duquan moving in with Michael. And while Randy's fate was horrifying on first viewing, the more I watch it the more I realise he wasn't screwed over by the system, he was screwed over by an implausible convergence of circumstances.
So I'm wondering could they have wrapped up Season 4 a little more conclusively and the show had ended there? We'd have seen Omar happily ride off in to retirement (and be spared Butchie's death), we'd not have the downer of seeing McNulty returning to his old ways....the only happy ending we'd miss out on would be Bubs, but again, season 4 could have ended another way without what happened with Sherrod.
And in season 4 there's a subtlety about the youngsters being a kind of origin story for the more established characters. As brilliant as the final montage of season 5 was, I think it's fair to say the subtlety had gone.
Would people have preferred it to end after Season 4? Or do we need season 5 for more closure?
