@orclover : I am not trying to "shoot down" your proposal. Detailed reviews or just more detailed descriptions of a performance would of course be beneficial. My point is merely that, in my estimation, it would be neither simple nor cheap to provide something along these lines.
@tresk : Ah, I think I see what has happened. You seem to have interpreted the "anal" tag as meaning "this show is analy orientated" when all it means is "there is some anal content". Totem have not deliberately misled you but you appear to have misunderstood what the tags indicate. As I understand it a tag, any tag, does not indicate that a card makes a major feature of anything, merely that it is present, for some unspecified duration and intensity, in the performance. For some tags, such as "cop" or "big boobs" there is little difference between the two possible interpretations (though I suppose that a show in which a police uniform was worn for a few seconds in a single clip would still be tagged with "cop") but for others, such as "anal", "stockings" and "bare feet" there can be a lot of difference. It would be better if the true meanings of the tags was clearer so that there were fewer misunderstandings.
Please, also note that tags like "anal" also serve as warnings to those who want to avoid whatever is being tagged I vaguely remember that was why this particular tag was added in the first place, but I could easily be mis-remembering.
