I don't mind not having a number score, many reviewers I enjoy watching don't use one, like mathewmatosis and runningshine.
The problem is that there is so little to work off of, you just go to other reviewers to get an idea.
It's an old review, but a better example was his super paper mario review, which was just a fucking trainwreck to put it lightly.
The game is highly praised on its story.
Also, if that is a quality of the game that you enjoyed, maybe add it to your review to be complete?
It's already bad enough he skips multiplayers, but that was ridiculous.
