It may not be considered top-tier Hitchcock, but To Catch a Thief does offer the irresistible charm of watching Cary Grant and Grace Kelly gallivant around the French countryside. It also might be the most beautifully shot of any of his films that I've seen. Both of those factors go a long way for me, and I found the story (while simple) to be pretty engaging. It's a more laid back Hitchcock, which works just fine for me. And that rooftop finale? Perfect.
