I stumbled across this movie on Netflix, and watched it because a "Delaware beach town" was mentioned in a review. I lived for several years in Rehoboth Beach, DE.
As far as reviewing the film, I won't. I seldom follow any reviewer's recommendations as I find them to be totally useless. Nobody can tell me what I'll like or dislike; I must find that out for myself.
The biggest reason I am adding my 2 cents is that "an abandoned lighthouse" is mentioned in several places as the spot where the two characters meet.
In actuality, the "lighthouse" is a submarine lookout tower which was used in WWII. These towers dot the seashore along Delaware's east coast.
Anyway, I did enjoy the movie and will recommend it to friends, if only for the familiar scenery. I especially liked the brewery tour in the Dogfish Head brewery as I have sampled many of their beers in their bar/restaurant in Rehoboth.
