I picked up this set in order to complete the gang. The quickest way to doing so requires purchasing this and the Mystery Machine. After building all the components of the set, I was overall pleased with the outcome. The minifigs are all great. You have Scooby and Shaggy, which come in all sets. Then, you get Daphne, whose hairpiece is quite large, but true to the cartoon. Velma is so far exclusive to this set. All of the members of the gang are true to their cartoon appearance. You get three monsters/bad guys in disguise, all three of which are derived from the classic original Scooby Doo series. The Black Knight is well done with the creepy eyes. The vampire is that of the classic expectation of what one should look like, and the ghost is very nice with its glow in the dark feature. The unmasked villians are on the opposite side of the monster heads. Needless to say, this is a nice assortment. There is a motorcycle vehicle with sidecar in the Mystery Machine colors. You can detach the sidecar to end up with a turquoise blue motorbike if you wish. The house itself is well done to give it a cartoony spooky experience true to the theme of the series. If you like purple, there are plenty of assorted parts in that color, including door panels. Be prepared for lots of stickers, most of which are applied to the window pieces to enhance detail. The clock face is also made from the stickers. The mansion itself is made of a greenhouse, entry way, kitchen, room with a safe, and the tower assembly. There is a booby trap in the entryway, a rotating feature which makes the vampire appear to change into a bat, a man eating plant (kind of like Little Shop of Horrors), a treasure map, a key, and maybe some treasure. If you are looking for a Halloween themed setup, this could be an excellent choice due to the spooky house, monsters, and two of the new jack-o-lantern pieces included. Overall, I would easily recommend this to kids fond of the show, nostalgic seeking adult fans like myself, and those who desire a Halloween themed Lego set.

The Mystery Mansion set brings the zaniness of the classic Scooby-Doo characters to life in LEGO form. Fans will love creating and staging displays inspired by classic Scooby-Doo storylines.

Recommendation: meh 3 / 5 by Nick Martin

Really, the best thing going for this set is the ability to complete your collection. It's hard to justify the cost, even with some very nice parts in the whole thing. It's an interesting set, but not interesting enough that you're going to want to leave it displayed on a shelf. If you're like me, you do the review, grab Velma and Daphne to put in your Mystery Machine, and part out the rest.

There is a huge amount of play value and the model looks superb from the front, with a lovely colour scheme and some offset building techniques which brilliantly represent the ramshackle nature of the building. The price of £69.99 or $89.99 seems very reasonable considering the number of minifigures and the piece count of 860 so I have no hesitation in recommending this set.
