Lost its magic after season 8...
In the first 8 seasons the scenarios were more gripping, suspense stronger, the acting was better and we got to focus on the passengers more. Not to mention, in the latter seasons they tend to crash the plane quickly (not much focus on passengers and character development).
Now they seem to be turning a slight plane scratch into an 'Air Crash Investigation' episode (i.e. Qantas).
Btw, the Air France one in season 12 reminded me of the show's golden era episodes (season 1-5)...
