Twin Sitters is a 1994 comedy that centers around two body building twin brothers who are hired by an informant to protect his twin nephews from the people he's informing on.
I'm sure a lot of people are probably not a fan (if they've even heard 0f) the barbarian brothers films led by Peter and David Paul, but I've always loved them. Twin Sitters is a silly comedy that gets a lot of inspiration from some of the classics of the genre like the three stooges, so the jokes are quite childish ad goofy at times which some might not find all that funny. The premise is simple but effective setting up the Barbarian Brothers with plenty of comedic scenarios to play with, and a fun atmosphere to thrive in.
This movie won't go down in the history books as an amazing film, but it is definitely a fun watch for the whole family. If you haven't seen Twin Sitters before, give it a chance because the kids should like it if nothing else.
