It is important to keep in mind that a less good pinball machine is still a pinball machine.
The bad ones are still good.
Also, every game is not for every person. Just look around on here and you will find at least one person who dislikes every great game. There's also at least one person who loves every "bad" game. Not a fan of Gold Ball myself, but haven't played it more than a couple quick games. I do like Popeye though.
