The Marketing masterminds behind this campaign are quite devious.This disk does not contain all realms as the product description leads you to believe. It only contains Storm and Swamp and NOT Cavern and Lava. This disk basically contains the 3 episodes that it has released via the individual disks with the cars.Apparently, the other realms will come available with individual cars to be released at a later time. Then Hot Wheels will release those two episodes on a disk, and then release yet another disk that MAY contain it all.My Kids were excited about this release expecting to get additional programming, only to be disappointed that there is no new footage on this release. There is no resolution to the story line on this DVD.In addition, you can not skip through disk, you can only fast forward.
