Summary
I initially held off buying series 4 as memory recalled that it fell far short of the highs of the previous excellent 3 series.
Although they did adapt a slightly awkward special guest feature, if you give it a chance you will see that many of the sketches still manage to be brilliant and Steven Fry's hilarious play on words has rarely been better.
Although this series did get a lukewarm response when it originally aired, giving it a re-run shows that it is well worth having all 4 series.
