I'm sure it will start with a good thematic story by ents, and then marketing will come and add 'Alton Towers Resort' every 2 minutes in the script and add how amazing their rides and attractions are, completely ruining a potentially immersive story.
I hope we see a theme/story along the lines of 2013's show, with the improvements of 2014's show with new effects added such as the waterscreen and fire. I liked seeing new elements added to the show last year (bravo to whoever decided that), although disliked how the 'story' became a 20 minute advert (blaming you, marketing team). Pyrotechnics were lacking too and it would be nice to see more. Although I can understand with budgets and Merlin it isn't entirely possible to add more.
Maybe they will have something linked up with the Enchanted Village this year. A part of it dedicated to Nemesis would be great too if they're going down the marketing route again. Although in my fantasy world I dream of seeing a story that draws you into another world and leaves you after 20 minutes feeling mesmerized and in awe of what you've just seen. Again the 2013 story left me with a better feeling at the end than the 2014 show did. I would prefer to see them go down more of the route of the older Towers shows, back in the 90s and early 00s, I think ents as they stand now are more than capable of creating stories as exciting as back then, permitting marketing leave them more room to create a good show.
