its difficult to say his style has changed for the better. this is his third 'morphed' show.
i believe the first was No Reservations, which mightve fit what IG wanted, learning more about the place, and more primarily about food. the place tho becomes secondary, including the people he reacts with and/or explore with. this is where he met the russian besty he has a gazillion times.
second was Layover i think, which is also a bit younger too, about a year or so also under the CNN name. very similar to Parts unknown too.
his earlier shows were much better, and quite frankly, more 'in tune' with what i want to watch.
IG, might want to try hunting for an older show called
Global Trekker
Ian Wright is my favorite host on the show...
and/or The lonely planet.
Padma Lakshmi started on this show ...
Both outstanding shows....
