Warning: This review contains several passages in which the reviewer (me) gets preachy.
Don't expect 73 straight minutes of the warm and fuzzies when you sit down to watch the new HBO documentary "One Nation Under Dog."
The documentary debuting Monday night, subtitled "Stories of Fear, Loss & Betrayal," is quite often painful to watch, but there are some uplifting moments to save you from total despair. And it should be required viewing for anyone who owns dogs or aspires to own dogs.
The film is sobering and fairly depressing, but it's the wake-up call about dog ownership that Americans need (and I'd argue the same themes touched on here apply just as strongly to cats).
