Star Trek Is Still Dealing With Discovery’s Klingon Damage

That's what happens when a story that is completely unrelated to another franchise is grafted into that franchise in order to cash in on the name value. Can't be too surprised when there are significant departures from the original material.

My headcanon is that Discovery never happened and can be ignored.

I like the Klingons in Strange New Worlds. They fumbled a bit with Discovery but they listened to fans.
