“Downhill” (*1/2 out of four) was a downright awful comedy about a married couple (Julia Louis-Dreyfuss and Will Ferrell) who embark on a family vacation in the Swiss Alps and barely survive an abrupt avalanche which causes them to re-evaluate their marriage and their place in life. Both Dreyfuss and Ferrell are pleasant enough but they face an uphill battle with a paper-thin and pointless screenplay that has no insight and hardly any laughs. Swiss Alps scenery is pretty but there’s not much else to keep you entertained. A weak remake of a 2014 Swedish hit “Force Majeure.”
