When I did the Yes discography, I listened to every album critically, which includes finding both the good and the bad. Familiarity can bring acceptance, and after listening to Open Your Eyes a few times, I found a fair amount of good. The songwriting wasn't great, but it didn't send me running from the room screaming or anything, and it was more Yes. More Steve Howe's finger-lickin' pickin', more great Yes harmonies, etc. I was fine putting it on and letting it spin.
Sure, the Keys to Ascension releases are superior, but I hate statements that are "I don't like ______ because ______ is better." By that logic, only the best of anything can be liked, since it's better than the rest. Keys being better has nothing to do with the worth of Open Your Eyes.
