To be honest, there were times in BF where I forgot it was set in Kanto. Like all the time. Most of the places the characters travelled to were anime exclusive, and there was very little call back to any past events from Ash's last journey there.
However, I think this ultimately worked in BF's favour. It was a continuation of the AG groups story in Hoenn that just happened to be set in Kanto for advertisement reasons, so I don't think there was any point in trying to emulate the tone of the original series.
