Reviewing Betas as a representation of the full game is quite underhand I feel, that to be is no different to looking at the box art and saying a game sucks.
Also the lack of consideration of the fact that there's a thousand things happening on screen at once is amazing, this annoys me immensely when GameTrailers and the likes crap on Wii games because they don't look like HD games. They always make a comment towards it and it really pisses me off. This isn't journalism, it's just stupidity.
