40 minutes. No more no less. Come on guys, there's other fish in the sea. Great visuals at times. Sometimes it was too visually busy to make out all the details. Imax is usually used for sweeping landscapes or giant buildings, subjects that are too large for regular film, but this film dwells a little too much on the close up. Perhaps if they backed the camera up more often, we would appreciate the ridiculously close close ups they used. Jim Carrey is WAY underused. They needed to let him riff more and perhaps sacrifice the G rating. Overall worthwhile.
