Review of all 4 episodes:
It is quite strange that this opens with an overly long panning shot across Brighton beach that is totally pointless. Especially strange as this is the opening scene of new Showrunner John Nathan Turner's era and one would think he would want a more interesting, striking, exciting or funny opening. The opening we get is pretty dull and odd. After that we get a flawed adventure which never reaches top standard and has various aspects which are weak but overall I feel it is overly criticised. I think it is okay. It is quite entertaining, especially in the middle parts.
The tone is far less zany and comedic than the Graham Williams produced era which had just ended and has a more serious feel along with efforts to be intellectual and use high scientific ideas. It is not all convincing and some of it seems a bit flaky but the ambition is admirable.
Tom is better in this more reined in style in my opinion but the script often fails to let him shine. It is interesting and dramatic when he gets aged by a machine and that is the highlight for me.
The plot is decent and the Argolins who run a leisure complex with hidden things going on are good in concept. They look a bit over the top but it works okay while the ideas of their race dying out etc work well. The Foamasi are cleverly used as unseen mysterious characters who seem menacing and intriguing until they appear fully at which point the costumes let it down.
There is plenty of good acting from numerous cast members and the dialogue is mostly fine. Romana and K-9 provide support and moments of camaraderie.
Overall I find enough of interest to make this a reasonable effort.
My ratings: Part 1 - 7/10, Parts 2 & 3 - 8/10, Part 4 - 7/10. Overall - 7.5/10.
