Is there a game that eventually CLICKED on that you previously just didn't get ?

I'm curious if you've ever played a game at least a couple of times, that you didn't like. Or that didn't make sense to you , and then it all just clicked and 'fell together' ? I don't necessarily mean a complex game that took awhile to grasp the rules of. But a game that you understood HOW to play but just wasn't fun, or didn't seem to 'hum' until just suddenly it just did ?
