I have to say I quite enjoyed it. I also feel sorry for the people who think you'd get the same experience watching it on Youtube. Is the story still going in a predefined direction no matter what? Yes but there's still a lot of room for variation in-between. Especially this time around if the dev interviews can be trusted. They've said that your decisions are going to matter more this time around than for TWD.
When I'm playing the game, I'm making decisions, I have control over what the main character is doing and it's far more absorbing than watching a video of it. Nor is it the same experience every time either. I've played it all the way through twice now and there were some pretty big differences between the two playthroughs.
The biggest and most unexpected being a part where I had to examine a room for clues to try and drag the truth out of someone. The first time I played I thought I had exhausted all my options and was only left with roughing up the character. I did so and hated myself for it and everyone else hated me for it too. Second time around, it turns out there were more clues I had missed the first time and the whole thing went down a lot more amicably. Now I have to live with the fact that I scared a child needlessly on my main save. You can't get that kind of experience from watching someone else play.
On a final note, if you were able to play all the way through TWD without forming any kind of connection with Clementine there's something broken inside you.
