If it exists there is probably porn of it, however if it exists there is probably a review of it, and a review of the porn of the it. However I have found it is entirely possible to really enjoy something but be unable to review it. I am not talking that how I should probably avoid reviewing high end medical equipment as I am not a medic/biology lab type (I can review the engineering and the user interface but that is not so useful when I can not tell you if it would work for what it actually needs to do), likewise there was that wonderful six months I spent reviewing the various sub orbital flights available to the paying public but I am no longer able to do that because it was a bit costly and I am sure others have similar stories. To that end what should we not rely upon your opinions of? I will quite happily review games, TV shows, films and books, though I do enjoy some utter trash in all of those, but never ask me my opinion on concerts and live events (comedians, plays, stage shows...) -- I pretty much always leave buzzing (probably should invest in some ear plugs and stay out of mosh pits) and if I read a review of them later then various people always seem to complain up a storm. In many of those cases they might have even had a point as one of the bands might only have had a 45 minute set thanks to an equipment failure. I do not know if it is because I leave the house intending to have a good time or what but I do tend to have a good time, I have a slightly similar "problem" for games and the other things mentioned but I can usually turn it off there.
