Calling Blackpool tacky isn't really an insult though, indeed, tacky is what I'd expect from a British seaside park...
This tacky level is seen in the dark rides, I wouldn't say that they are all of top quality though... Alice in Wonderland is so crap it's fab for example... Aside from that there's only 4 others and even then they are not what I would call top quality...
The TLC is only a very recent thing though to large quantities... Nick Land has made them have to revamp the park a lot (and has probably brought in the income TO revamp bits and bobs), the state of Beaver Creek beforehand was dire...
And let's not say they keep all their classic rides, otherwise what about the Whip, Turtle Chase and Noah's Ark?
