Ever had a No Name Pizza, because there was no brand name stuff in the freezer? Yeah, Big Brother Canada was kinda like that. It did the trick, but not as good as the real thing.
It trended on Twitter for like a half hour, but for all the wrong reasons, as mentioned above.
I fear it'll be much of the same for The Amazing Race Canada, which I'll probably watch too.
Your metaphor is flawed, because here the 'no name' pizzas are better than any of the name brand frozen ones. They are raw, made daily on site, covered with fresh ingredients, cook up more quickly, taste great, and happen to be the most affordable.
The Canadian version of Big Brother was surprisingly on par with the US one by any objective review. It had the same scale, scheduling, airings, feeds, and extended coverage. It had the same scale and production values. The only objective difference would be the prize value.
Before this aired, it would have been easy to speculate and assume it would be 'Canadianized' with deep cuts. One could easily have predicted a Big Brother Canada being shrunk to say 8 people, living in a smaller apartment, for half the time. Games might have been in the realm of a cheap ring toss. Somewhat to my surprise and to their credit, they maintained the larger scale and production values.
Personally I find the games and contests hokey, but objectively I can say they were on par with the US ones.
And I can recognize when effort goes into the production. It strikes me when you have costumes, special effects, large pools of goo, spray showers, huge moving rigs, etc, that does prove a certain amount of production effort. I defy anyone to blast water into a gigawatt studio for hours without electrocuting someone - it's not trivial.
