[EX Q]: Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!
[EX A]: Negative

[EX Q]: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.
[EX A]: Negative

[EX Q]: Not much of a plot differance from the 2nd one... I saw them film in Chicago in 2010... That was the only cool thing about this movie, the Chicago back drop... Other then that don't buy this unless you saw it and liked it.. If you haven't seen it just rent it!!!!!
