As a piece of engineering (like many construction projects here), I think it is impressive. Apart that is from the lack of backup systems which it first opened, leading to that embarrassing incident with people being stranded for hours. But hey, they saved a few bucks on the budget.

Can you imagine the meetings after that... "Quick - let's figure out who else we can blame for this..."
I remember watching it being built over serveral months from the vantage point of our
condo at the time, which overlooked the site. An interesting process. But it just lacked something for me. I loved my trip on the London Eye years ago, but somehow we've never quite got round to doing the Singapore Flyer. We even had some free tickets once but ended up giving them away.
