Are Before Watchmen and Doomsday Clock worth reading, or do they ruin the legacy or are they Dogshit

I’m a big fan of the original Watchmen and have been debating whether to check out the prequels (Before Watchmen) or the pseudo-sequel (Doomsday Clock). I’ve heard mixed things — some say they add depth to the story and characters, while others think they miss the point entirely.

I’m not expecting anything to fully match the original, but I’m curious if any of these are actually worth my time. Are there specific stories or issues that stand out, or is it all just cash-grab nonsense? I’d love to hear honest opinions from people who’ve read them. Are they a worthy continuation/expansion of the universe, or should I just stick with the original and leave it at that?
