Problem: I think MATTEL needs to fire the team who makes all the Batman toys, & hire a team of people with quality & creativity in mind. This one of many Batman toys my 6 year old son has, every 5 minutes he comes to me to put the toy back together agian. (I glued together last years modle of the car, the 'wings' always fell off!) the cave is very top heavy, with a flimsy support & backing. If you don't have a permanent wall space to stick this toy on to it will fall as soon as you walk away! Plus there are three pices to this toy that would fall off as soon as I put on that we didn't need anyway.
Solution: Negative
