“Instant Family” (** out of four) was a hapless comedy about a couple (Mark Wahlberg and Rose Byrne) who find that they get much more than they bargained for when they adopt three foster children (Isabella Moner, Gustavo Quiroz, Julianna Gamiz) which leads to numerous complications for them and the children. Charismatic cast helps and there are some scattered laughs but film becomes more tiresome and contrived as it goes along and final third really rings false. Octavia Spencer is solid as always in good supporting role. Third teaming of Wahlberg and writer/director Sean Anders but this cannot match their first collaboration “Daddy’s Home” which this sometimes resembles.
