If you like Brit drama/comedy(or even if you don't, particularly) then you'll go for this ongoing prime-time soap opera set in an English country village - unlike the "Street" the accents render the dialogue comprehensible, so I cannot tell you the location.
The characters are diverse, interesting, and believable. "Heartbeat"'s hero, an ordinary British bobby is neither Sherlock Holmes nor Dirty Harry...he simply gets the job, done, dealing with from poaching to blue murder through daylight robbery, as does the series,itself. The episodes are distinguished by low key writing resulting in high-key entertainment.
I never discuss the acting in any given review, and sometimes wonder why other reviewers bother to. I assume that the cast in any production is performing splendidly. After all, if you're in the 4 % of the thousands of aspiring actors who actually make a living at their craft, you gotta be good!
