“Float” (** out of four) was a middling horror psychodrama about a vlogger (Kate Mayhew) and her friends (Kaya Coleman, Grant Morningstar, and others) who embark on an annual river float in commemoration of the death of their friend but are besieged and stalked by a mysterious local (Matt Wise) and his sinister followers who want them out. Overall well-made and well-acted for this genre but film gradually sinks and fails to stay afloat because of its own generic story and script. Directorial debut for noted horror producer Zac Locke.
