Come on, the term "boring" is so incredibly subjective... some might even find black and white scenery interesting. A film is ruined when the film doesn't work anymore. Removing sound would ruin a modern film. But reducing 5.1 Surround Sound to 2.0 Stereo Sound doesn't ruin a film. Heck, TOS was supposed to sell color TVs, which is why it's so colorful. Yet most people watched it in black and white, where, for example, the uniforms are not distinguishable. Still didn't ruin it for them, I take. It wouldn't even ruin Schindler's List if you removed the colored dress.
