Replace TotT completely, but keep the TotT name. what lies within just needs to be put out of its misery after 8 years.
Keep sub species as it is, but change a couple of scenes as they did this year so it's not predictable. more actors too. keep the finale where it is as it was fun watching people run out.
Get rid of skin snatchers or sort out the finale. tone down the actors a little as I was actually more scared of getting hurt by the actors pushing me about than the actual scares. don't care if it returns or not, but would rather have this than another year of what lies within.
Replace freak show, but perhaps use the props in a kids scarezone of some kind. It just wasn't scary in anyway.
I liked dark apocalypse, but I think it's had its time. three years would be a long run for a scarezone. wouldn't mind something like scary tales return (both the style of the zone, and the theme).
Keep house of monsters. just use feedback from this year to make small improvements, just keep it even if it means wobble world doesn't return.
Lighting this year was very good, I don't think much more needs doing really.
