As with the previous Playmobil Advent Calendar that was Back To The Future themed, I did not open up one window per day. I carefully opened the whole box to use all the pieces immediately. I loved the specific outfit versions that came in this set although I felt like maybe they could’ve added a few more people, like Mad Dog Tannen’s gang. What I didn’t like was the stick on hood dressing for the DeLorean. I feel like they would’ve been better off somehow clipping it into the wheel arches instead of using the sticky pads. Aside from that, which really isn’t a big deal, this set is well priced and a really fantastic addition to the Playmobil Back To The Future collection. Well worth the price. Tim
