A scientist endeavors to prove the existence of parallel dimensions by inventing a machine that provides a view through a portal to some of these alternate dimensions. During a demonstration of the device, something goes awry, and a bunch of people find themselves in the middle of what seems like an earthquake. But the reality of their situation is far worse. The machine has teleported them all to the dimension they were watching. From the title, you can guess the alternate universe is not where most people would want to spend their vacation.
One of SyFy's better efforts; the action is well handled, the creatures are designed and animated well, and the acting is above average. There's an ironic twist near the end, but too many clues make it pretty obvious long before the twist is revealed. The parking meter bits were actually clever, although the explanation for them was goofy.
The weakness is the formulaic approach: the characters are eliminated in the usual one-by-one manner of these type of movies, usually just as they say or do something stupid. It's usually obvious who's going to get it next, especially the clichéd knuckle-headed greedy guys in the group.
All in all, not bad for a TV movie and considering the weak theatrical releases out this summer, and the ticket prices that look like they were set by a big-oil executive, watching this for free is the better option.
