I personally thought that series 4 was one of the best and most consistant series since the show returned. Its was great story after great story, with one of the best Doctor/Companion pairings that the show has ever had. Every series has duff episodes, but this series, imo, had the least of the lot
I'd have to agree with this to be honest. Of the first four series, series 4 was for me the only one which was really consistent. It was also the only one where I started to really like Ten as the Doctor
