Last decade or so, the UK has produced so many versatile and dramatic (mini-)series that one must unavoidably compare and choose between them - as time is limited and eyes must relax from time to time. Sometimes you tend to forget what you have seen already - due to several recurrent actors, often in similar roles of coppers or crooks - the trend that is usually characteristic to smaller nations, in Scandinavia in particular.
Undercover sets in rather intensely, but then it scatters and wears away somehow, and some standpoints and attitudes are pointed out too often and too strongly, but then the thrill resumes and last two episodes form a real cat-and-mouse play, without becoming too "explosive". True, using flashbacks with a little effort to change the performers' outfit and looks for the period of 20 years brings along unnecessary confusions and disruptions, but all the major performances, however, are good at least, and Maya Cobbina QC by Sophie Okonedo deserves more praise and attention she has achieved so far.
The ending scenes are a bit odd, and the very ending made me the inspiration that another season would be launched, although there is no hint of it so far. Anyway, I would presumably find time for follow-up, but it is okay to cap off here as well. Let the big echelons be more visible in other series... :)
