Caveat: I can't fully "review" these plays, of course, because I can't understand 95% of the script. For the same reason, I can't fully assess these plays against any other Mirage material that hasn't been translated into English, so please take my thoughts with the appropriate grains of salt.
In a word, I loved these plays. They're very successful theater: wonderful use of lighting and sound effects to create very much the same level of physical excitement I personally get from a big budget movie. It's a great way to bring a text with comparatively small financial pull to life (and I'd love to see more of this in the fine arts). The acting, in general, is very good and the characters very in character. I would recommend these plays to anyone who is a serious Mirage fan. They are an important addition to the universe. I laid down a fair amount of money (~$160 USD) to buy them and get them shipped from Japan, and although I am not rich, I consider it money well spent. They're that good.
