Visited Thorpe twice this season. It's still very much possible to have a fun day at Thorpe (provided you visit on a quiet, off peak day) but wow some areas are just sad at the moment. Visiting Chessington and then this place one after the other is such a stark contrast, one looks better than it ever has in the fairly short time I've been going, whereas Thorpe is almost exactly the same as it was last season. The only real changes I noticed were the interesting Tidal Wave changes, which I'm honestly not sure if they're good or bad, and on the second visit some leaves had been cleared from a fence at Colossus.
It is worth noting that on the second visit, lots of effects were fixed. Off the top of my head, the water effect on the heartline roll on Saw was working (I've only ever seen that work once or twice if ever), Inferno had it's mist back, Swarm's plane, fire engine and helicopter had mist (no water or fire though 🙁), and the water tower at Tidal Wave. Nemesis Inferno has been brilliant every time I've ridden it this year, I honestly think it's just as good as Nemesis now, although that may be recency bias as I've not ridden Nemesis in a while. It also has it's old soundtrack back, with the new one playing in the station, which is good. Audio all around the park was very loud, sometimes too loud. It's basically impossible to have a conversation around Colossus, Saw and Stealth. Old Town is in a really sad state, with Slammer more visible than last season, the rotting corpse of Loggers behind a fence, and with quite a bit of Creek Freak theming still up. The tents over the picnic benches have 'Creek Woods Sawmill' on, and there's wanted posters everywhere. I saw from Samurai that there's still some bears up around Loggers, except one has fallen over, which is sad and kind of a metaphor for the whole area. Black Mirror Labrynth has a cool sign but the building isn't pretty.
Overall, I still think Thorpe can be quite fun on quiet days, but, and I know I'm stating the obvious here, the park is crying out for some TLC and most importantly something new.
