Kroll criticism

Review for all 4 parts:

I think this is a very underrated story. It is nothing special and pales in comparison to the greatest serials but it is a perfectly decent, standard adventure in my opinion rather than the weak disappointment that others seem to see it as.

The storyline of The Doctor and Romana searching for the next segment of the key to time on a planet being exploited by outsiders for its resources and encountering an uprising from the natives as well as a giant swamp monster is a pretty run of the mill setting for a filler story but is a reasonable enough plot. The thing that lifts it for me is the writing from the great Robert Holmes. It is nowhere near his best work but it has good dialogue, some thoughtful themes, some believable writing of characters and some smart humour. The acting of the 'swampie' natives is nothing impressive but not awful and their poor visual creation with green make up and dreadlock wigs is really the only issue that really stands out as silly. I think that given the restrictions of the age and budget that is forgivable. If you replaced the swampies with effectively created alien natives it would eliminate that issue so is it really a major problem? I feel the writing is strong enough and the acting decent enough to gloss over the visual shortcomings. The swamp beast looks poor by the standards of the best technology of the time or by modern possibilities but I feel it was a decent effort for the age this was made and it is a fun creation with some enjoyable scenes of its attacks.

There is an ecological underlying theme of exploiting resources and lack of regard for nature or indigenous people as well as another element of superstition versus science. I really enjoy the ideas and dialogue. I also enjoy the political clash of the human characters who are well acted with the wonderful Phillip Madoc especially convincing.

Tom Baker and Mary Tamm are as effervescent as ever as The Doctor and Romana and while the story is no classic it is a solid serial in my opinion. I am a bit sad that it gets a lot of criticism.

My ratings: Parts 1 & 2 - 8/10, Part 3 - 7.5/10, Part 4 - 8.5/10. Overall - 8/10.
