Series 4

I did enjoy the vast majority of Series IV, and I can't deny my love for Donna - easily the best companion of the RTD era, no contest. We should all be supremely glad that Davies' initial plans for the S4 companion didn't pan out, if you ask me. The Sontaran Stratagem/The Poison Sky was a gripping story and the perfect way to bring back one of the best of the classic villains, The Unicorn and the Wasp was one of the most enjoyable stories of the revived series, and Midnight is quite honestly some of Russel T Davies' best work ever, period.

But for me, the series finale ended up going from a powerful start to a HUGE let-down as far as story was concerned. Sure, it was great seeing everyone again and bringing Davros back was incredible to see, even if how it was done was a tad iffy. But in my opinion, there was too much going on at once, and the entire story just felt rushed and loosely held together. Donna's departure was far less than the character - and the actress - deserved; the second human-form Doctor was contrived and more than a bit silly; and the bit with Rose was little more than pandering to the mass of fans obsessed with the idea of Rose and the Doctor shacking up. In my opinion, the finale needed to be either three episodes long, or they needed to cut out one or more of the returning characters (the SJA cast would've got my vote for the boot, especially Luke).
