Central Park - Massaker in New York

Nutter at large at night in Central Park. Bunch of teenagers go for a romantic stroll and then stuff happens. Them's the basics. Actually you've got a plot to explore with that but this is poorly put together. I suspect the budget is partially to blame for the lacklustre way it plays out but sad to say some of the acting ain't all that either. One piece of advice given the ending left room for a potential follow up......please, DON'T.
