One judge thinks it is heavenly, the other says it stinks, judges giving perfect scores after they themselves point out several flaws, on the other hand they give 3/10 after disliking just one thing while praising everything else that's been done. Judges hating everything that's been done, but then scoring it 7/10 across the board, thus artificially keeping the contestants close to each other. These are just examples, and once you start noticing it, you can't stop noticing it happens in every episode. Contestants' words or actions get twisted so they seem unsympathetic, others say or do the exact same thing but they get a free pass, every build is the hardest of them all (till the next one comes along), every couple is racing till the final second and then drops dead having finished it just that second, but before that they have time to play around and talk to the camera for hours not doing any work, it's made to look that everything's filmed in continuity, but then they interview the couples like they are reacting on things that happened seconds ago. It is so flawed. It has now even gotten to the point that only judges choose the winner (no public voting any more), so it's no longer a game show, but a carefully planned out script where the winner can be predetermined before the first hammer has been swung. I used to love it, but once you start noticing these flaws all the time, the fun is over. It just gets worse every year (especially the judging), to the point I decided I won't watch the next season
