Watchable for the group of familiar 40s character actors, but after a reasonable crash sequence, this movie quickly loses its bearings. It's hard not to see some similarities to GILLIGAN'S ISLAND and LOST, but the awkward mix of on-the-nose comedy and drama never quite works. Lots of story lines, none of which really come together. The sequence at sea in the second half is the last momentarily interesting section, but it's quickly jettisoned like so much flotsam. Ending is particularly sudden and illogical.
SPOILERS AHOY If the ship was unable to reach landfall the first time, how come everyone assumes they will easily be rescued on the second attempt? It seems more likely that everyone (including the soon-to-be-married main couple) will die given the arduous passage of the first unsuccessful attempt. Or, perhaps I missed something obvious because my attention drifted away long before the sudden and seemingly tacked-on denouement? Either way, if you choose to partake of this doomed flight, you have no one but yourself to blame.
