Yes, Rabbit Run is almost unendingly depressing and gives very little hope for humanity. The main characters range from the disturbed to the despicable; however, all of them are extremely believable. Updike paints a picture of the protagonist, Rabbit Angstrom - a self-centered infidel, a lousy father, who by all means ought to be completely unsympathetic - and yet I can genuinely empathize with him. Ultimately, I think that Rabbit is redeemable. Also, Updike's prose is - as always - spare and beautiful, and though he tends to only write about one topic - WASPs having affairs - he does it well enough to make it almost universal.
