"I haven't found Bart very useful or fun for game play. I believe I've run across puzzles where his small/hatch access ability and target shooter ability combo would have come in handy, but I solved the puzzles using a combination of other characters.
While I realize that the gravity/soapbox car model is intentionally asymmetrical, I rebuilt it with the addition of other pieces to both clean up the design and get it down to a size when it fits in the Plano fish lure/tackle box I use to store my Dimensions toys."

Thanks for the feedback!
We're sorry to hear that you were not particularly fond of this expansion pack. By the sound of it though, you understand the beauty of building with LEGO: If you don't like how one build looks, rebuild it or modify it yourself!
"I was extremely excited for this fun pack and while the expansion pack is decent and functional, it doesn't really have anything special to it. The model itself looks really good. The car was well-built and the minifigure looks nicely detailed. I have two big gripes with this pack. The first one is that it doesn't give much content. Homer and Krusty are both more competent and have more abilities to make them worth getting and they also have access to the Simpson's world. Bart can crawl through vents thanks to being a short character but that's pretty much it. His slingshot doesn't have that great of accuracy. But the deal-breaker for me here is Bart's lack of voice clips. In the case of characters who didn't get new voice clips like the 1-11 doctors, audio from the characters' respective shows would be used to give the characters lines. Bart however, is completely mute. He didn't even get his signature line, "Don't have a cow, man!" which I find to be disappointing and it makes the character seem boring."
"I Was Super Excited To Here About The Homer Simpson Figure Coming To Dimensions, But I Did Not Know Bart Was Coming! Bart Is My All Time Favorite Character In The Simpsons. And When They Made They Lego Simpsons I Purchased It Right Away (Thanks Marcos Bessa For Making The Simpsons). And Was Happy To Receive It. But Now Back To Bart. His Soapbox Derby Looks Amazing And Cool I Appreciate The Detail And The Printed Pieces. Bart Is Also A Great Minifigure. I Also Love The Fact That Bart Can Fit In The Soapbox Derby. Overall Its A Great Fun Pack. Well That's It For This Review And Feel Free To Check Out My Reviews. As Always Have A Great Week."
