It's hit and miss, it's a decent service but the questions are usually leading and straightforward - you won't get much insight into events that you couldn't normally guess the answer to. Questions are similar to:

The Everton fans are great arn't they?

You get 5 minute reserve highlights too, no under 18s or ladies' games.
Some people have been complaining about the quality of the video after a recent upgrade - I don't know if that's been resolved.
