It's not that it's unpopular, but the UK / European market, where the machine would appear to be a natural, shrank considerably when the lack of training mode and attendent Category A operational approval became evident. The helicopter was accepted by the CAA as far as type certification was concerned, but not for operations, because you can't do on-site training with it.
Wasn't there a UK time-share operation that was going to use the machines? What happened to that?
Most other operators seem pretty happy with it. It is a smooth, reasonably fast machine, and flies pretty well. But like all new machines, it ain't cheap.
The real competition for the EMS market is a used Bell 222 - carries about the same load, also reasonably smooth, and much, much cheaper.
