It is the best Grand Prix to attend though... if im going to be sat at one corner for an entire race anywhere on the calendar it's going to be 'tabac/louis chiron', there's not a better sight in motorsport than an F1 car creaming it through that section.
Granted it may not deliver in terms of overtaking or close racing but when you're sat at one corner for an entire GP you miss most of the drama anyway and its generally a nightmare to keep track of everything that's going on like you would be able to from the comfort of your sofa at home. I find most people go to F1 events just to see F1 cars driving on the limit rather than in the hope of seeing lots of overtaking etc... hence why you regularly see packed out stands on parts of the track where there are never going to be overtakes.
On top of that its obviously a stunning location and just a great place to visit provided you don't mind dipping into your life savings
There's a reason why everyone involved in F1 looks forward to it so much, it may seem underwhelming to some people on TV but in person it's utterly amazing. Im a sucker for F1 cars driving round street tracks though, I adore Singapore as well.
