Mother (1996)

After his second divorce, narcissistic science fiction writer Albert Brooks moves in with his mother because he believes it’ll give him the opportunity to work through his problems with women. Debbie Reynolds as the titular mother is adorable and eternally patient while dealing with this judgmental interloper into her home, along with visits from his brother Rob Morrow who brings a whole other set of issues. The grand experiment revolves in ways that are beneficial to them both, which at least makes the irritations of the journey not so bad in the end.
