Speaking as someone who actually was a full time digger on Great South Bay in Patchogue during the era of this movie, I can say to those who weren't, you will not get very much of a handle on what life was really like for us, not that I didn't recognize a lot of the characters in this film. I do applaud the filmmakers for their effort on trying to recreate as much of the clammers water world as they could with the budget they had to work with. The few period clam boats they could find were fairly accurate even if many were way underpowered with what looks like 15 horsepower period engines.
I of course enjoyed the few Long Island locations they used like the Silly Lilly and abandoned Cerullo's fishing stations. That said as a movie it was just OK. Not awful, (you want an awful 70's movie made in the 70's? watch "Two Lane Blacktop " sometime, but it was certainly not great either. The sad commentary I think is that like the industry that once supplied 70% of the worlds shellfish and is long gone, the days of trying to make a movie for a million and half dollars today are long gone too. It seems to me the cast and crew gave it an honest shot though.
