They made episode 1 free for non backers just to let people get a look in at what they're missing.
The episodes are pretty interesting, one of the aims of the project is to let fans see the production of a game from start to finish, so I would recommend a watch even if you don't like the look of the game of point and click adventure.
You can still become a backer via donation through paypal which gets you a DRM free copy of the game (PC+MAC+LINUX), access to the forums and you get to watch more episodes of the documentary.
Please disregard Greg Miller, don't worry, he only appears in this episode for like 5 seconds.
