The gags ignite largely. Go for a change not to Calvin Klein, but Clint Eastwood ;-) And Jules Verne is of significance or better Jules Verne &. High Noon at 8 clock in the morning, the stupid Biff as a gunslinger, and a fascinating steampunk locomotive. All this there to marvel at.
Whether the film is childish? Yes. But he is also the spiritual young at heart.
