I really, really wish I had loved this story. I think the concept of setting a story in an amusement park is actually incredibly noble and would have worked beautifully on the screen, whereas on audio it ends up being fairly middling, not actually doing very much. I absolutely adored having the Doctor and Peri actually having fun together- I wish they'd ditched the mediocre plot for the sake of giving us more of it. As it is, however, it's... Fine. Kind of unengaging, to be honest. I wouldn't consider it a great starting entry, yet the potential for the range is more than obvious.
