Wow, is mostly all I can say. I feel this episode is basicly the height of all that TTG has given us so far.
It's smooth, tons of stuff to explore, extremely interesting and captivating storyline, lots of interaction, all locations are easy accessible, all puzzles makes sense, none of the old annoying characters took part of the story and you added some new ones that it is tons of fun interacting with.
I can't be more satisfied. This was a really, really, really solid performance. Job well done.
