I know there is work involved in media based attractions, but I would quote Jon Favreau: "the problem is not CGI, but directors who don't know how to work with it". He was referring to people complaining about CGI in movies so much. He attributes at some directors not knowing how to handle the tool. The same thing happens in rides. As I've said, when done right they blow you away, but more often than not, screens and projections are used as a crutch, a cop out.
