I can see why a lot of people are annoyed by the constant focus on the Green Team and Team Texas. That's probably why the editing is viewed as being awful. But there was one very good thing about the rivalry: Team Texas burning their Express Pass on the Roadblock instead of at the Detour and then finding out the Hours of Operation! That was funny to me!
No Belle Book, that is precisely NOT the reason why the editing sucks.
The editing has been slowly falling by the seams beginning TAR25.
On TAR25/26...
-Not all teams are shown reading the clue when they get it
-Not all teams are shown departing the Pit Stop
-Not all teams are shown in airport scramble (they already get on the flight and it sucked)
-Not all teams are told of their placement upon checking in at the Pit Stop.
On 27 so far is is 100% worse because...
-It has all the problems above and more
-The editing is just so sloppy, you never feel like it's a proper Race. We would stay at a task for loads of minutes, then the minute a team gets to the next task, we get a lot of focus there, and all the other teams are just shown as "getting their clue" in the most basic way possible of just flashing their name with the CURRENTLY IN XTH PLACE subtitle.
-There is simply too much focus on the tasks rather than the competition. It is always more fun to see teams chasing after each other getting stuff rather than see them do a task.
And the thing that 100% sucks is that the Secret Scenes (more so this season than 25-26) have all scenes that could have been edited in for an amazing episode. A lot of the Secret Scenes are definitely good and would have helped the show. Full scenes such as teams getting lost, the reveal of a reason that eliminated a team, a team having a meltdown on an otherwise uninspired Detour are all on the Secret Scenes, and it really is mind-boggling that they would choose to omit those amazing scenes and keep terrible ones in.
So yes... TAR needs to step it up with editing. Even if the tasks aren't culturally relevant 100% of the time, the editing would really help! (See 24 Kuala Lumpur, arguably my favorite leg from that atrocity of a season... bad, culturally irrelevant tasks and some of the teams were total garbage but very fun editing and competition made it a good ep)
