I agree with you Jack, it's Hasbro's blame if they put out a weak product and it doesn't sell. Not the consumer.
The dome itself was nice, as was the Womp Rat and the vaporator. But that really was about it. Then they threw in some junk figures and raised the MSRP on it. If they had just made the Owen and Beru new figures, this set would have probably done fine.
Or, they could have done this instead for the figures -
- VOTC Luke
- TAC Jawa
- two new droids
Or hell, go the route of crispy Owen and Beru as a couple of piles of bones instead of the Womp Rat, and make the set include 2-3 Sandtroopers rather than just one... even make a variant dome with battle damage (burn marks). I know I would have probably bought both versions then.

Something like this would have made the set much more appealing I think. Putting in figures that are well over a decade old was a dumb call on their part.
Hopefully this isn't the end of sets like this and they can look at a similar format in the future. Given how Star Wars is a gold mine for them, if anyone has the resources to make something like this work, it's Hasbro.
