Didn't think much it to be honest. Tried (a bit later than we should have, admittedly) to get to the Pier Head from the Albert Dock side but were turned away and advised to go round the back of the Albert Dock (as in, right round).
Inevitably, the view was a bit crap round there due to the big wall that runs the length, but reasonable enough to get a feel for the display.
My feeling was that the two sets of fireworks were too far away and too far apart - you couldn't take in both at once (perhaps not the point) and, because of the distance, felt it was happening "over there"...part of the spectacle for me has always been looking up into the fireworks but this was just like watching it on television. Safety concerns of course acknowledged, I'd actually have preferred to be in the larger crowd with a worse view - at least for a bit of an atmosphere.
I'd be happy to see them back on the parks next year, though I can appreciate that the river display scenario playing out ideally does sound good.
Anyway - bit late in here but I thought it worth posting for posterity!
