Pinks all-out is watchable, since it's more of a bracket racing format. If you like junkyard Rustangs or S-10 pickups that have been given a cheap paint job and a used motor that might or might not make it through 5 passes, then the original Pink's might be better.
As with everything that's on TV, it's all about the money.
Without the trash talking and the sandbagging, it would be even more boring, since they repeat every show at least a dozen times before shooting new shows.
