Are you fucking kidding me? Gazza (and others) provide a perfect explanation of exactly what a car park coaster is, and you still want to argue the point?
If the brain cells in your head replicated themselves about 40 billion times, it would be exactly half a brain.
You wonder why you're being 'attacked' and picked on - take a look at the post I have quoted, and the post from Gazza. This is your hacking discussion all over again.
Green Lantern WAS NOT built on a carpark. Yes - It WAS built outside the existing park boundary - but the boundary has been extended to include it - just like the boundary was extended to accommodate BuzzSaw (which is also not a carpark coaster). No parking spaces were lost to the construction, no roads diverted (except DURING the construction - and that was only temporary to allow a safety envelope) - by your definition, the fact that Lethal Arkham has a roadway (for the studios) running next to it - IT is a carpark coaster... better yet - SUPERMAN is a carpark coaster, because the track actually passes OVER the old studio tramtour route.
Pull your head in and grow the fuck up. If you don't want to be treated like a child, stop acting like one, accept that you are wrong (because this is not the case of 'your opinion' versus 'someone elses opinion' - it wasn't built on a carpark or over a carpark so it's not a carpark coaster. You don't like it - fine - theres plenty of others who do, so I doubt MW management are going to cry that one CHILD doesn't like their new multi-million dollar attraction.
Now shut up.
