The ending to Episode 5 was a hopeless bungle.
Lee's great "sacrifice", chaining himself to the radiator, is a preposterous mistake completely at odd with The Walking Dead universe. Worse, it's no sacrifice at all. First, it's unimaginable that Clem, if she even survives the city (and recall that we forgot to, you know, actually tell her how to find Omid and Christa--oops!), won't be forever haunted by the image of zombie Lee chained to a radiator in a windowless room for all eternity. The big deal he makes, that she shouldn't shoot him, is horribly, horribly misguided. Putting down someone before they turn is extremely cathartic. It was a point of honor, pride, and closure for Carl to put down Lori in the tv series. They got it exactly right there. In the game it completely spoils the whole ending, since Clem doesn't get that closure.
Second, are you kidding me? We're left with no cutscene, no reunion with Omid and Christa where we see Clem finally escape? It's clear that TTG badly rushed the entire episode, from the incredibly brief playing time to the pointless recycling of locations, but this was the worst sort of failure--betraying a fundamental point of The Walking Dead universe. It played exactly as though the developer simply hit the wall of a deadline and had to quit without finishing.
Very, very disappointing.
