Dallas Bella was absolutely gorgeous when she first started providing over a decade ago or so, she even has some of the pics from that time in her images. Providing has caught up to her in beauty and unfortunately, took that fresh look away for the most part, and that happens to the vast maority of the ladies in this business.
The OP is right and is entitled to review a provider as he sees fit without comments from the peanut gallery telling him how he should do his review. Of course, not writing glorious reviews, especially of well established providers opens you up to a YMMV label put on you by the Eccie dick clique. And since most guys want to be in the popular crowd, dickstroking other hobbyists, then the shitty sessions go unreported.
