Had a flick through this. It is just screengrabs from the pilot movie with comic style speech bubbles etc. For what it is, it's very well done with a good layout, decent lettering, clear screengrabs. It is, however, ultimately completely pointless in this day and age. One for completists only.
Hopefully IDW (or Titan) will put out originated Animated material at some point.
I was disappionted to find this wasn't original stories, but I picked it up anyway. I haven't seen any of the new cartoon and don't want to on youtube, so I will have a different perspective to people who have seen the episode(s). What sold me on getting it really was how well done it seemed to be. It really looks like a 'proper' comicbook to me - I've seen some of these screenshots with dialogue comics before that make it really obvious what they are, but top marks to this one on all the factors Ralph's already mentioned. And it was 'only' £5. Anything much more and I wouldn't have bothered.
I hope they do do some original stories in this format, though. The Star Wars books in the animated style were great.
