“East Of The Mountains” (** out of four) was an uninvolving adaptation of David Guterson’s best-selling novel about a retired heart surgeon (Tom Skerritt) who learns he has terminal cancer and then takes his dog out with him for one last trek into the wilderness as he seeks to end his life on his own terms. Beautifully filmed by Sebastien Scandiuzzi and with a few effective moments scattered throughout but this goes South pretty quickly, as it meanders and dawdles. Mira Sorvino is wasted as Skerritt’s concerned daughter. Similar story was covered more richly in 2015’s “A Walk In The Woods.”
