I can count on one hand the number of movies I've turned off, this is one of them. It may have made an adequate sitcom, Ellen locking herself out every time she went outside was our first hint especially as she managed it with a dead bolt lock that requires a key to lock. The best thing is thinking about how all the mature actors got to return to the set to relive better days and much, much better scripts. I wouldn't be surprised if they'd simply filmed the actors when they were 'backstage' they wouldn't have gotten a far superior film by far without insulting the audience's intelligence.
If you want to watch movies with more mature actors may I suggest anything with Olympia Dukakis' or something made by British movie makers? The Last of the Blonde Bombshells, both of the Marigold Hotel movies, anything with Maggie Smith in it, or even some of their TV shows like Vicious as apparently in the UK people don't automatically become feeble, suburban sitcom clichés after 60,
