I can't speak to all of his reviews because I did not read them all*
However, it was obvious from the few I did look at that he went into the experience predisposed not to like it ... then he emphasized all the things he found that fit with his predisposed negative view ... in the end, even though he found a few things that were "nice", he went with his predisposed position and did NOT like them.
I could do the same thing if I were to review flying, eating seafood or some of the other things I do not really care for. Most of the time, if you go into something convinced you won't like it ... most of the time you won't.
* I guess you could say I am predisposed not to like his reviews so I didn't bother to read any more - I mean, since I didn't like the ones I did read, like him, it only follows I would not like the rest even if I did find something positive in some of them.
