DCI Barnaby and DS Jones investigate the apparent murder of Emily Harte who was run off the road by a car while cycling late at night. The evidence at the scene also suggests that the driver then backed up over her to make sure the job was done. She was a member of the local cycling club and was in a relationship with George Jeffers a professor at the local college. Barnaby quickly concludes that Jeffers was the driver's intended target. Jeffers had several people who might want to get at him. His ex-wife Melanie felt that she was losing her son as he too was spending more time with his father and Emily. Then there's a disagreement with a local technology firm that has built a new air traffic control system built on his theories. Jeffers thinks there a serious flaw and has threatened to go public and the company's CEO Clinton Finn has already taken steps to get the college on his side by endowing a new research building. Throughout all of this, someone locals have dubbed the bucketman... Written by garykmcd

'Midsomer Murders' goes cycling
18 February 2017 | by (United Kingdom) – See all my reviews

As has been said by me a number of times, 'Midsomer Murders' is one of my most watched and most re-watched shows. It is nowhere near as good now and the Tom Barnaby-era wasn't alien to average or less episodes, but when it was on form or at its best boy was it good.

Season 12 is a watchable but hardly outstanding season, few if any of the episodes reaching terrible level but the best episodes of the season are just pretty good. As far as the previous Season 12 episodes go, Season 12 started off well with "The Dogleg Murders" and "The Black Book" was decent. "Secrets and Spies" this said was a just above-average episode that had interesting ideas not used to full potential. With this episode, "The Glitch", it's nowhere near one of the show's worst episodes but there also isn't enough here for it to be one of the best episodes.

Have nothing to complain about with the production values, as always they're great. The idyllic look of it contrasts very well with the story's grimness, and quaint and atmospheric photography. Nor with the music, the music fits perfectly, with some lush jauntiness and sometimes an ominous quality, and the theme tune one of the most memorable and instantly recognisable of the genre.

The acting is also very good. John Nettles and Jason Hughes are both superb, individually and together (their chemistry, and the chemistry with Daniel Casey and John Hopkins before Hughes, being a huge part of their episodes' charm). Not everybody likes the characters of Joyce and Cully, have never really had a problem with them and feel that Jane Wymark especially and her chemistry with Nettles gives the show a lot of charm and welcome humour. David Haig, Nigel Whitney and Phillip Jackson do fine with what they have. The climactic cycling scene is a lot of fun and tension-filled, and there are some intriguing twists and turns that give the episode a not-what-everything-seems feel.

On the other hand, "The Glitch" is yet another episode to have too much padding, not just in the first half an hour but throughout. Not all the padding is interesting, with either a drawn out feel or just written in a way that makes the viewer indifferent, and not all of it is relevant. As a result of this padding, a general lack of colourful or tense atmosphere and that material varies wildly in interest and relevance, "The Glitch" can drag.

Was also, like previous reviewers, very underwhelmed with how the episode ended. A real shame too because the build up was great and the culprit was a shock (though the motives were as dull and clichéd as one could get), but how the case is resolved is rushed and abrupt in finish, almost like the writers were in haste to write the ending and forgot to finish it. Much prefer it when the supporting characters are colourful and eccentric, and not the dull or annoying or both ones you get from time to time, the latter being the case with the generally lifeless supporting characters in "The Glitch".

In conclusion, not a bad episode but dully average in a way. 5/10 Bethany Cox
