I know many Brits grew up with this show, so it's a fond childhood memory for them, and if that's the case for you then by all means take a trip down memory lane.
If (like me) you read the books first and then found this series, I'd recommend skipping it.
My 5 star rating is generous, and based on the first season alone. Season 1 covers the book 'The Animals Of Farthing Wood', and with the exception of a few gender swaps (which I understand would've been to attract more female viewers) it is a fairly accurate representation and decent viewing.
Season 2 is based on the books 'In The Grip of Winter', 'Fox's Feud' and 'Fox Cub Bold', and here's where things start to fall apart. Characters that survive the entire book series are killed off while characters that are killed off in the books survive the whole series.
Season 3 is based on the books 'In The Path of the Storm' and 'Battle For The Park' (with a tiny hint of 'The Siege of White Deer Park') and it's pure rubbish.
Weasel (with her insanely annoying voice) is promoted to main character for some reason. The plot BARELY resembles the source material, and begins to contradict itself. Characters go missing for no reason. I could go on...
Bottom line, if you want to read a wonderful series I couldn't recommend the books by Colin Dann more than I already do...just make sure not to watch this series directly afterwards.
