Chances are Hollywood won’t be making Dumb and Dumbererest, so The Brothers Solomon will have to do. Will Forte and Will Arnett star as socially inept siblings who decide to have a baby via artificial insemination in order to continue the family line. The pair makes for a fairly anemic comic team, with Arnett mostly rehashing his boor routine from “Arrested Development” and Forte delivering few good lines, even though he wrote the script. You get the feeling the actors are enjoying each other’s company far more than we are enjoying theirs.
