Reviews are, after all, mostly opinions. And like noses, we all have one. 8) And remember, that the written reviews are one persons impression out of the thousands who sailed on the ship... even on the exact same journey! I venture to say, that those of us who post, even among the regulars with large post counts, are in the minority as far as reporting their experience on a message board. I venture to say that the majority of cruisers on a voyage have little or no knowledge of the existence of cruising message boards.
Reviews are worth reading, they are not worth fretting over.
If something jumps out of you - ask for more feedback from the members here!
If there was a serious issue, there would be multiple threads and multiple responses in a very short time.
IMHO, it is beneficial to read the "good and the bad" - gives you perspective.
