I'm not sure how the ending was a cop-out, when I think of a cop-out I think of something not planned or made up as they go along. I feel they pretty clearly knew what the flash-sideways were from the begining of the season with Rose telling Jack "Its okay, you can let go now" being one of the first scenes of the season. While I was surprised by what the Flash-sideways ended up being, I do think it was in keeping with some of the early themes of the show, especially Jacks inability to accept death in the first season (The loss of his father, not giving up on Charlie after Ethan hung him even though he seemed long gone, trying to chop Boone's leg off with that door instead of admitting he was going to die, etc.), although I do think on rewatch it will give the 6th season kind of a jarring presence going back and forth between the two timelines. I agree that it wasn't of the series' very best episodes, but it still a very good episode. It had some really strong emotional moments, as well as as some very cool action and epic visuals.
For the series as a whole I would have a hard time being convinced that this is not the best drama of all time on American Broadcast TV. Personally I think it may be the best show period but that it really a tough thing to decide going between genres and taking into account the different times that shows came out. I know a lot of people think shows like The Wire, The Sorpranos or even Mad Men are all better, but I think while they are all great they don't quite match up to Lost as a whole.
