Whilst I'm not a fan of the Angry Birds IP choice, the addition of Dodgems/return of Cinema is a good idea for a park severely lacking in 'dull' rides...
A shop for Stealth is good as well, mainly as it lacks one, and also because Merlin know how good merch will be purchased by the visiting guests...
It's a shame Thorpe's imagination doesn't stretch well towards minimal investment years... But I don't really see THAT much wrong with their additions, as it's poor planning and focus that has resulted in them needing such additions in the first place...
