I agree with you. I think that it is difficult to determine the playability of a game if the player or reviewer does not have the skill level to play the game the way that it was intended to be played. Obviously, not everyone is going to be at the top skill level, but I think that the developers create the game with the intermediate or advanced player in mind, not the reviewer with five minutes of experience. It all depends on the intentions of the game designers, but, for the most part, I agree with the above post on the topic.
I think that those types of games have a good resonance with children; in my experience, most of my playthroughs of those types of games were when I was younger and had the time to devote and perfect my technique for little reward other than getting to the end of the game.
