I watched the series finale of 'Greek' like I watched most of the episodes of its 4-season run: With a drink in hand, uncontrollable guffaws, and just a few tears streaming down my face.
At its core 'Greek' is lighthearted, snarky fun. It deals with issues that other shows turn into Issues, from underage drinking and gay relationships, to cheating and graduating college. As I said goodbye to these slightly caricatured but totally lovable characters, there was more than one point that I thought "See, this is what this show's about." And I was referring to 'a story about siblings,' 'a story about the real love of your college life - your roommate,' 'a story about love,' and a few other half-dozen plot points they managed to sneak in there. And that's the beauty of it - it's about everything, so there's always something to be invested in. It's (it WAS) sometimes predictable. It was sometimes really (really) not. And it was always (always!) enjoyable.
There's a very good chance you've never seen an episode, and, for that, I'm jealous. Because (if you're smart), you'll start fixing that soon, and you'll get to hold onto it a little while longer.
