While having moments of greatness, 'Taggart' was on the whole just not the same in the Burke period. Especially the later episodes, where there was a real sense of the show having gotten tired from running out of ideas and lost what made the Taggart and Jardine eras as good as they were. As said, there were great latter Burke period episodes, such as "Pinnacle". There were also bad ones, a notable example being "Genesis" (one of the worst episodes to me).
It was great to have an episode that centered around Burke, he took some getting used to and was hit and miss as a character but when he was developed he was handled very well. "Compensation" and "Judgement Day" are proof of this. So is "Trust", one of the best episodes from this period and one of the not many great ones. It has been described as a near return to form for 'Taggart' and cannot disagree personally. There is plenty to love here.
My only issue with "Trust", something that was very common in the later Burke-period episodes, is the now rather out of date and not very well fitting music. It was fine in the 80s and 90s and fitted then, at this point it was at odds with the action and like 10 plus years too late.
However, the photography is both gritty yet moody, very well suited to the story's style, and the location is striking yet suitably unforgiving. The theme tune is hard to forget and still works, it's the background music that doesn't work and there has been nothing held against the theme tune.
Writing is thoughtful and entertaining, while also not holding back on the uncompromising grit. The case is never too simple and it is not convoluted either, just the right amount of complexity. It is also very hard hitting and pulls no punches, appropriate for a subject matter like this.
Burke's character development was appreciated, while Alex Norton gives one of his better performances of the show and has great chemistry with Phyllis Logan. The latter of whom giving the best guest turn in a while.
Concluding, excellent. 9/10.
