This reminds me of some reviewers I've looked into over at IPDB that gave some popular machines something like 2's across the board. I'd go look at the summary of their ratings and their average rating of all machines would be something between a 3 and a 5 out of 10. Okay, so if the average rating of all the pinball machines you've played and rated is that far below average, maybe pinball is just not for you. Give it up and go find a new hobby, like golf or bowling.
Maybe some of these raters are just joking, as some of these same raters will rate a lot of the usual top 20 pins ridiculously low, then pull out all the stops on ratings of machine that are usually considered turds and rate them really high. Who knows though? Perhaps these raters are serious, and they happen to make-up some "pin turd army" that I've known nothing about up to this point, with their mission being to knock every-one's favorite pins off their pedestals and replace them with turds.
I don't want to name any of these so called "turd" machines, because honestly, even the worst pinball machine I've ever played still provided some fun and entertainment for me, because "Hey, it's pinball", and I like pinball.
