Does anyone know what movie this is?

When I was a kid my mom or dad got it at blockbuster and it was supposed to be a kids movie but looking back, it didn't really seem child-friendly exactly... I can't remember big details but I remember possibly a dysfunctional family, a grandpa or dad that drank something called "grog" the kid in the movie might have been adopted... possibly a scene where the kid got locked in a closet or abused or something? does this ring any bells? the only part i remember for sure was a grandpa/dad drinking something called "grog"
