Highly enjoyable adventure which is supposedly based on the real events of 1943 involving the USS Eldridge. Of course there is no evidence to support the stories but the spooky possibility of it all is still fun to think about and actually adds to the films enjoyment.
Yes it looks pretty kooky now with lots of errors and dodgy effects but like many old films that's part of the fun. Actually the effects for the time vortex aren't too bad and the shots of the vortex hole in the sky with lots of swirling cloud around it are quite good still.
The acting is very basic and hokey with chief of cheese Mr Pare and one of the Queens of the 80's Nancy Allen both in a very soppy love plot, lots of military types running around being ordered by lots of scientist types haha its all very cute.
Its really the perfect boys own adventure with a love interest, daring heroism, mystery and a happy ending which can't fail to make you smile..it will also make you wanna jump through time vortexes too hehe.
