[Q]: Just "assembled" the bat cave for my 5 year old. Pathetic construction and workmanship -- half of the gimmics don't work. Another pile of injection-molded plastic parts and stickers that I get to assemble -- what is this thing -- $4 of raw materials + $2 of shipping + $10 of marketing? Garbage. Shame on you Mattel, the only thing worse is the batman figures with the batarangs that take 30 minutes and a blowtorch to get out of the packaging. This batcave will collapse and die within hours of play, I'm sure of it. GARBAGE!
[A]: Negative

[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!
[A]: Negative

[Q]: If you're a Dolly Parton fan (even somewhat of a fan), this is a must have for your collection. It will NOT disappoint!!
