One emoticon describes this season perfectly;
It seems like every time there was a situation where time was of the essence and their very existence hung in the balance, they awkwardly acted as though this was not the case and proceeded to go into forced and completely unrelated dialog which would do daytime TV proud.
More like "Lost in Peyton Splace". If it wasn't for the mostly very nice CG, and what little actual plot substance there was, I'd have called it a complete miss. What was there was decent, but it was floated by effluent. Then again, maybe it's just me being me
