Query: Is this any good?

No... NOOOOOOOOOOO!!!!!!Lots of potential sadly blown. It's like somebody serving up a great big wonderful cake with a big steaming turd on the top. It might look lovely. It might look like the best cake ever in the history of cakes. You might even be able to eat most of it perfectly happily.But at the end of the day, you would be daft to do so. Why? Because it has a turd on the top, stupid!
