The five main actors do a great job with their characters. Most of the time, they all play their characters straight, and you will laugh because you have probably met people a little like them. Maybe even you will recognize some of them as your neighbors. There is the Vietnam vet who has all the 'toys' and gets a little trigger-happy when his neighbor's dog soils his lawn. There is the fellow who really believes that his neighbors are part of a demonic cult. There is the buddy-buddy neighbor that comes to visit unannounced at breakfast and helps himself to everything including the leftovers from the night before. There is the dottering old fellow -- who lets his poodle 'fertilize' everyone's lawn. There is the straight guy (Hanks) who thinks his neighbors are weird, but would rather just not think about them.
I picked this up fully expecting another dud that I would have to peruse with judicious use of the fast-forward button. I was very wrong! Despite being stupid, really quite stupid with an inane plot, I nonetheless found myself laughing until my stomach hurt in many places. This is slapstick humor a little in the Coen brothers tradition, but without the vulgarity. So if you don't like that kind of humor, for example you didn't laugh during say 'Something About Mary' then you ought to stay clear of this. But if you do, this would be a fun movie to rent with friends for a night of light and meaningless comedy.
