On the subject of the fireworks themselves, I thought they were fairly average in comparison to previous years. There wasn't as much as a wow factor, the runs around the Eye were pretty weak and not as refined or as well used as they were even last year. The only redeeming feature was the "sky puke" finale, which was appropriately over the top - must have been great to experience it in person.
Once more the BBC's dire coverage blighted the TV viewing though. I don't understand why they feel obliged to cut between different angles every 10 seconds, especially to the pointless crowd shots! Just leave a wide angle camera on for the entire display so you can see it properly!
