Cause it's not. "Dr Strangelove is regarded as a black comedy classic (I love black comedy, don't get me wrong), but it does one thing wrong. It doesn't make you laugh. Oh, there are a couple of good moments, "gentleman, you can't fight in here, this is the war room" is a classic line. Peter Sellers playing three different characters holds no value to me. Kubrick's "Spartacus" is much better. (If you like this one, see other overrated movies like "The Wizard of Oz" and "The Maltese Falcon".

Arguably the best black comedy ever made, another Stanley Kubrick classic still holds its place in the greatest and most influential films of all time for its original humor, relevant messages, and much more. There are some inappropriate parts, but only subliminally, not directly. The opening shot, the secretary in the bikini, the "playboy" magazine, even the DVD cover, etc. But kids won't notice or understand scenes like this. As with most Kubrick films, it depends on the person watching.
