After watching it a few times and reading the reviews both here and elsewhere, I though perhaps it was time to attempt a balanced view of
AOL/WW3, element by element.
HUMOUR:
The contextual humour - i.e. the things we were meant to find funny worked OK for me. The things that were supposed to be "internally" funny (like the Slitheen's toilet humour) didn't work too well for me - but I still feel it wasn't supposed to work for the adults anyway.
PLOT:
With holes big enough to drive a Death Star through (which everyone and there auntie have mentioned, so I won't take up space), it could be said that this was classic
Who 
. Luckily my suspension of disbelief just about made it to the end credits. This was mainly due to the fine writing of the little scenes and the detail given to the Mickey sub plot.
ACTION:
I felt that the action was a little too sporadic, and was mainly used to turn a 60 minute story into a 90 minute one. The "Benny Hill" type chases through a box set were not all they could have been. After repeated watching it started to feel like a studio bound story, which is a great shame given the breadth of the alien "crash landing" in
AOL
DRAMA/CHARACTERISATION:
Although it was there, the tension never really built up as it did in the last two episodes. This can only be laid at the door of the director. The script had a lot to offer in terms of character exploration and exposition. We learned quite a lot about Jackie and her relationship with Rose, and the same cam be said for Mickey/Rose. Jackie is coming across as the kind of woman who needs a man to validate herself. Rose is no such person - she has a deep affection (perhaps even love) for Mickey, but she does not need him to make her whole. Mickey is growing on me - I actually want to see him again, if only to find out if he does have any ulterior motives.
Harriet was a gem of a character - I'm just a little confused as to how the Doctor knew who she was yet seemed to know nothing about the Slitheen gambit. Still having post-regeneration memory problems? Her journey from "only a back bencher" to leader of the nation was a joy to watch
SFX:
Great for the crash landing - loved the pig - not bad for the missile - a bit lacking for the Slitheen. As nearly everyone has pointed out, the CGI/costume mix left a lot to be desired. Having said that, does anyone remember Mestor from The
Twin Dilemma? [shudders]. That was utter crap by 1964 standards, let alone 1984 when it was first shown
ARC RELEVANCE:
Apart from the Bad Wolf tag, this story has apparently added nothing to the overall arc of the season. I say apparently because a few of the throwaway lines (Mickey/Ricky) may well come back to bite us in the bum later. As the Doctor says "Everything's important"
OVERALL:
Not as great as we would have like it, but not as terrible as some have made out. My faith in the series has not abated - in fact there is a certain comfort that things will get better.
After the feast that was episodes 2 & 3 we should have expected a sorbet course before tucking into the chef's special.
Barry Letts (one time writer, director and producer for DW (among other things)) said that writing good drama was a bit like the letter W: you start with a high point, work your way down to a trough and climb to another high. The Dalek episode will be that high. Working on this logic, I think we can expect a slight downturn at about episode 9/10, ready for the big finale.
