[EX 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!
[EX A]: Negative

[EX Q]: What else can I say? All that love CB should own this DVD. I love Charlie Brown and this is a true Christmas classic.
[EX A]: Positive
