Actually, TDPI is still pretty well-regarded despite not everyone being as hot on its cast now. And if you're going to watch season five, that's the one to watch instead.

TDAS sucked because it treated its cast like garbage, happily propping up a certain few as the most important above everybody else giving nobody else anything resembling a satisfying outcome by the time it was done. No character development, no resolution, nothing. It was a major disservice to some of the show's best players for a season that is titled "All-Stars". Plus while most of the cast was solid, ones like Sam were not. I know what you mean though, they didn't take advantage of having the two casts interacting at all. They could've done so much with that and what they did just added to the mess.

Also, absolutely nothing was accomplished when its story was done. Virtually none of its plots outside of that of the two finalists meant anything by the end. And theirs was a story already told once before so really, if you omitted this from the canon little would be lost by it.

TDPI has the most uninteresting cast, but its stronger and more developed members save it. And its plots for the most part are decently paced and don't wear out their welcome. Plots like Skave definitely should've ended sooner and Amy and Samey's rivalry was not given sufficient development. But as is it definitely did at least a better job.
