It does look nice in red and black, then again a fresh lick of paint makes anything look good. Actually, was Forbidden Valley's colour of choice always red and black from the start or is more of a recent thing with Merlin?
Anyway with some saying how the themes of both X-Sector and Forbidden Valley being too similar now due to them both being about a secret organisation running the place (Ministry of Joy and Phalanx), I could make the argument that there is a slight difference with them in which Phalanx is more military based while the MoJ is more MI5 based though I'd wonder if the park might be aware of two similar themes and that they would need to shake things which could be why X-Sector such as the state of Smiler is in the way they are in as maybe they are planning to give the area not a retheme but more an updated version of the theme being more sleeker let's say and that its better to wait until then to do it all on one go?
I've no clue what changes Forbidden Valley will see and I don't want to go off topic but I do wonder once Forbidden Valley gets its likely refresh next year, is X-Sector next to get TC? You could argue that if you ignore the additions of the Retrosquad, it hasn't seen anything new to the area since Smiler opened and is honestly due for some changes ahead and they might try and not make the two areas have a similar theme of secret evil organisations unless ofc they throw a curveball with the theme of Forbidden Valley next year but that's unlikely.
