Well the things I liked about this episode were the great drama, the awesome airport scenes and thing s like that which have been absent in most recent seasons. It was a breath of fresh air!
The drama was great - everything that happened in the scenes with Dave & Connr was really touching and hard to watch!
What I didn't like were the tasks. The tasks were awful. A driving or fishing detour is a joke, and the Roadblock was a mess... literally. Nothing about the tasks gave me the feel of New Zealand, which TAR has done really well with past seasons in NZ a long time ago.
The tasks were not impressive, but as a whole, the first three legs have been well above the recent average.
