War Of The Chosen: Enough To Be A Sequel?

In my last full video, I asked whether War Of The Chosen was priced too high for an expansion pack. Now that I've played through it all, I feel like I can at least give my opinion on that.
Please remember that, unlike in other territories, here in the UK, War Of The Chosen is priced the same as XCOM 2 was on release. I understand that elsewhere it is still expensive, but not to the extent that it is where I live.
