Edit: I snapped this after I found it. That’s how I knew it was on so tight. It still took me a good few minutes to find it because I kept looking under the car. I wasn’t expecting the filter to be on top.

The danger in overtightening is that you ruin the seal. So maybe not quite as bad as loose, but an oil leak is still a problem. Much like anything with a crush washer, you want to get it snug, then tighten enough to squish it, but not so much that you ruin the very thing that keeps it intact.
That’s not really so much of an issue. Virtually all spin on oil filters are designed in such a way that you can tighten them until the metal filter body contacts the sealing surface and the o-ring will still be happy and protected from over-squishing in it’s little recess.
All bets are off if you’re buying no-name filters tho.
