Pleasure Beach being adored by some enthusiasts and disliked by others does make sense though, since I feel the same about Thorpe. It's put on a pedestal by enthusiasts but I personally find it pretty awful, the only coaster I really like there is Inferno and in terms of other rides besides the headliners, there's naff all.
Blackpool is in my view a much better park than the others in the UK, the ride offering is much more complete and almost all the coasters are thrilling, plus there's the retro rides too. It's also important to remember the nostalgia for lots of people goes towards making a park feel special to them, growing up visiting etc.
As a town, I've never really had any issues with Blackpool, every big town or city has rough areas but the tourist areas of Blackpool (and to be fair any area I've been to there) are ace.
BPB for me hasn't been on form for a few years now, but after most of last year spent away from the park I'm very excited to go back.
