Personally, I am not a fan of TAR 10. Some of the good teams went out early, like Vipul & Aarti, Kellie & Jamie and Peter & Sarah. I hated the six pack alliance and found this part highly laughable, and I felt that some legs were very underwhelming, such as the first leg in Beijing, China, the second Vietnamese leg, Mauritius, Madagascar (as the Fast Forward teams were beat), the tenth leg (they should have stayed in Europe) and the eleventh leg (which spends half time in Morocco and the other in Barcelona). The final leg was also extremely disappointing for it's design.
Moreover, I despised the majority of the cast. I liked Rob & Kimberley, the Beauty Queens, and Tyler & James (to a point) but Lyn & Karilyn... Words cannot even explain. It did have a lot of potential, with the diverse locations and all but this season is where the lack of editing started to show. Again, this is only my opinion.
