I'm not sure that's a fair characterization. Happy Madison has released 35 films in theaters, and 30 of them have recouped above production in theater gross. That includes 5 films that grossed over $200 million, and 7 more at over $150 million. It's not LOTR money, but compared to the production costs of most of those films it's a huge profit. He may not be good at making great cinema, but Adam Sandler is undoubtedly good at making money.
