It is what it is.

"70s grindhouse about a hugely fat psychotic woman who is released by the mental hospital in the care of her grandmother who tries to control her eating habits. In addition, her sister is a prostitute who brings home her tricks. This obviously doesn't end well and the bodies pile up. Ethel then attempts to get rid of the smell and bodies with amusing incompetence until the final twist ending."

The butcher-knife double-murder scene is laugh-out-loud funny. Worth watching for the camp value.
