Daniel here.
I preordered the Blu-ray for Roger Rabbit in February, hoping for bigger things in store, not just the definition, but new things. I was hoping for everything to be sunnier in Toontown, hoping that with the movie back on store shelves, it would bring new fans. I still hope that.
But, there's some bits that you should know. If you want to know the special features besides the Hi-def versions of the three Roger Rabbit shorts, there's also the Before and After of Toontown feature, a thing explaining the Toon-stand ins, a commentary recorded years ago, and a few other things also from the 15th anniversary DVD set. Basically, the only difference is that it's in a better quality, the shorts were restored, and they put new menus and a loading screen with Roger's bowtie spinning.
And if you have both the 15th anniversary DVD set and the Blu-ray DVD pack, you basically have the same thing. The DVD for the Blu-ray is the first disc of the 15th anniversary set repackaged without the film reel look.
I have not lost faith in this set. Because of it I saw a few things I didn't notice before. Like, when Eddie Valiant is in the elevator, and it's speeding up, in one shot you can see an outline of The Road Runner, and a few seconds later you can see an outline of Wile E. Coyote.
With news of The Stooge, I hope they will do more with the characters of Roger and Jessica. But right now, it looks a little bit lessened.
