This extension is working well so far to display the likes and dislikes, but I don't know for how long... https://returnyoutubedislike.com/

How reliable is this?

Works fine for older videos where the like/dislike count was archived. On new videos, not that much, since it's dependent on data from other users also using the plugin.
