    Newbury Graveyard's Open Doors Day
    I would recommend this to a friend!
    Purchased for: Self
    We redid the Lego and our challenge was to find the right bricks because all the parts in one big bag! I wanted to show my nephew this set. My 9 year old nephew started to build the LEGO and I finished it in the evening. I also showed him how to play with the app, which he understood pretty quickly! It's a set that can be adapted to any monster, zombie, skeleton, vampire, that you already have. So, for those who have the minifig series, it's a perfect set. You can easily make a 'scary' set and expand the graveyard! What I liked about putting the set together was that I felt like I was reading a script when I turned the pages of the instruction booklet. As examples, I can mention the leaking faucet or the tree roots climbing up the right side of the shed. In short, this cemetery is not as quiet as you might think. It was a bit by chance that I discovered that the app was now working on my cell phone, so I was curious. Initially, I had missed the collection because the app was not compatible with my cell phone. We already had Jurassic World, Lego City, Harry Potter and the DC and Marvel superheroes. I'm really glad the app works, it's a great game!

    Hidden side graveyard
    | 25-34
    Purchased for: Son
    Bought this set for my son on Our trip to Legoland He was so excited to get home to build to it, only to start building it and found there where no stickers in the box and a few pieces missing. He was very disappointed.Would have returned only it was got in legoland. Emailed Lego about this issue but they never even got back to me. Very disappointed. He has been asking to get more of the hidden side from Santa but I’m very reluctant as I don’t want pieces missing from a toy from Santa!!

    My interest in the new Hidden Side theme is based on it's similarity to the old Monster Hunters theme. This particular set was the first I went with because I was drawn to the price-point and the graveyard design. There are a lot of fun playable elements built in and plenty of small details (like the inside of the gravedigger's shack) that add character to the set. The other reviews I have read mention issues with the app support only on newer phones. While I am sure the app adds something to the playability of the set, I really got it just for the design and pieces. While this new theme is obviously directed at children, I am enjoying the pieces and new characters. For anyone looking to add a graveyard to your own city, medieval town, or whatever, this set gives you everything you need!

    Great Set for Halloween
    | 45-54
    I would recommend this to a friend!
    Purchased for: Self
    As somebody who enjoys the season around Halloween, this set appealed to me. The features and details of the set are perfect for the spooky ghost hunting theme. There were very few stickers (a big plus). The most difficult part of assembling the set was the tree, and that was not very hard. In addition, the AR app was fun to interact with the set. I'm "on the fence" about buying other Hidden Side theme sets at this time, but I am very pleased with graveyard set purchase.
