As an AFOL and HP fan, this set hit many happy buttons but there are certain things that could have been done better.
Pros
I had many WOW and happy moments building the train and the platform. So many clever ways of using bricks etc in original ways. I especially loved the arches on the platform, the stack of coal in the tender and the seats in the carriage- brilliant. The detail is amazing on the engine, tender and carriage, with some iconic scenes from the films.
The track is a bit repetitive, but once I got into a rhythm I found it quite therapeutic.
Cons
The middle section of the engine is a bit wobbly or not as secure as the rest of the engine. The platform does obscure the train if in front and you can't see the platform when it is behind. I have put mine to the side. I do wish they had included an older Ron and Hermione rather than the two students. My BIGGEST issue is the plaque - which has the wrong locomotive model detail (apparently) but also King Cross Station??? It is King's Cross Station, such an important detail and it is wrong! When people are paying this amount of money, every detail should be checked, rechecked and checked again. I now have this at the back of the platform as it keeps drawing my eye. I have heard, and it may be a rumour, that Lego are going to update the plaque for the next run of the sets. I think it would be very good customer service, if those buyers who have the faulty plaque are offered an updated and correct plaque for free (proof of purchase obviously).
Overall
This is a display set, it is not a set to be motorised or to move around a cityscape. It is big and takes up a fair amount of space.
I used my VIP points to significantly reduce the price, so would I have bought this at the full price, mmm not so sure, but I had more fun with this than the Colosseum. Though feel a bit aggrieved as I was so disappointed, for another year, that it was not Gringotts. Please can we have Gringotts in 2023. Please.
