Miami Vice season quality

[gemhunter]

I have Miami Vice seasons 1, 2, and 3. I was going to get the last couple but read in a couple of places that "purist" Miami Vice fans felt the show started to jump the shark and don't recommend the last two seasons. Any input on this? It is probable that some day I will go ahead and complete the series, but I will put it on the back burner if it seems like I am buying them now just to complete the series.
