I have the same feelings about Untrue as I do about Super Mario Galaxy. Comes on a disc, promises and delivers entertainment, goes great with drugs, triggers nostalgia, etc.
But in the end I keep wondering "why am I chasing all these fucking coins anyway?" and "why is that crackly sound on everything?"
In both cases I think the accrued testimony of emotional response, all the critical theory references (err mostly for Burial, this one) and all the laboured mythmaking conceal what are essentially frighteningly shallow and falsely dimensional experiences. Burial's "London" is to the real London as Mario's Galaxy is to a real life Galaxy. In the final analysis they're very, very annoying places and not at all like the real thing.
