I dont know.. the sub itself is awesome.. but the selfiluminating pieces - its shows that they are not really shining light - everyone has seen glowing things move under water in various cinema cgi scenes..
Its just wrong..
Im painfully aware that if such critic was applied to jw- i would not be able to write this shadder (basically a glow, broken through a fresnell depending on the z-buffer(object), z-buffer(waterlevel)..
If only Behe-man was here to save the day..
