If you were told to watch a movie directed by Rob Reiner, starring Michael Douglas and Diane Keaton, with a budget of $30 mil. you could think that you are about to experience a movie with powerful emotions and an interesting plot.
Actually, in the end, this is a rather simple movie and its course is obvious from the beginning.
Michael Douglas plays Oren Little, a realtor who's about to retire after he makes his last sale, and Diane Keaton plays his singer next-door neighbor. What will happen between them is to be seen (I won't spoil it for you) but I'm pretty sure you have already guessed.
The acting from the 2 veteran actors is effortless but the direction from the once-mighty Rob Reiner is too simple and targeting more for a few easy laughs if nothing else. Note that Reiner is also in the movie as the pianist who plays for Diane Keaton's character.
It's a dramedy more than just a comedy but even the dramatic elements are more likely to promote laughter, if not anything else.
There a couple of good songs sang by Keaton (?) and you also get to see Grease's Frankie Valli in a cameo appearance.
Overall: It's OK. Douglas/Keaton are fun to watch, but don't expect greatness.
