The cast of TG America had worked into a rhythm and there was no need for a change.
Like Top Gear, if you change the presenters after they made the show their own, the reboots are doomed to fail.
Absolutely awful in every way. They took all of the stuff they learned from TGUS and threw it out the window. No chemistry among hosts (and arguably just bad hosts to begin with), cringe-worthy studio segments, B/C-tier celebrity guest stars, completely unremarkable and boring track - it's the same mistakes all over again.
Was there a reason they killed off history channels hosts and made their own? I thought the history channel one was made by the BBC.
I find the cast pretty annoying. They claim being cool, smart, fast, etc... While none of it shows up on the screen. And I can't stand that "murica" bulls**t, I'm ok that some people like pick-up trucks but don't start presenting it like a GT car for God's sake.
Who's saying a truck is a GT car? Is that satire?
I'm guessing The History Channel realized they could do another reality show for less money.
As to why the BBC did not hire any (or all) of the hosts, it sounds like they have another project in development so they may have been unavailable (or their contracts do not allow them to be on other automotive shows).
I may be American , but the pro America propaganda got old real fast
So the season finale is tonight, all I can say is thank god, there was not much good about this new TG America, it was over all horrible , I may be American , but the pro America propaganda got old real fast
