And we're onto the fourth part of this. Near the halfway point.
31: Spearhead From Space (3rd Doctor)
One of my favourite Doctors and as opening stories go, I love this one a lot. It's not big but it set up the 3rd Doctor wonderfully and began the establishment of his exile to Earth and joining up with UNIT. We also got the wonderful Liz Shaw and the debut of the Autons.
32: The Waters Of Mars (10th Doctor)
I had such low expectations for this special, so imagine my delight when it turned out to be one of the most daring episodes of the series. Okay, so the Flood weren't as heavily focused on as you'd expect but the character moments, including the Doctor's foolish Time Lord Victorious stance along with Adelaide's suicide certainly made this a memorable one.
33: Inferno (3rd Doctor)
For a seven parter, this one never dragged a bit. A parallel UNIT and a great big threat with those monsters and the Brigadier can be one scary bastard with his parallel counterpart, the Brigade. If I had to pick one flaw, it's that this is Liz's last proper story and they don't bother to give her an actual exit.
34: The Edge Of Destruction (1st Doctor)
Way before Midnight aired, we had this delightful little paranoia two-parter where the TARDIS were becoming mistrustful of each other. And all because the spring of the Fast Return Switch had broken.
35: The Talons Of Weing Chaing (4th Doctor)
I've not seen as many 4th Doctor/Leela stories as I'd liked to have but this one is certainly of high quality. Essentially a Victorian mystery, the Doctor even dresses like a detective in this one and Magnus Greel is a pretty interesting villain.
