It's a real shame this was the last we saw of Little Britain, but it's not as if it didn't go out in style. The USA series was just as good as the original series in my opinion, although while the original series is probably better overall, I must admit, a lot of the elements of Little Britain USA were way better than the equivalent elements of the original show. I particularly liked the theme tune being played in a higher pitch at the end, and the upbeat remix they gave to the opening theme. While it was a shame to see some old characters absent from this series (such as Mr Mann, Roy and Margaret), the new characters such as Phyllis Church and Mr Doggy were brilliant. I'm so glad they kept Tom Baker as the narrator though, it would be incomplete without him. It's a shame they never managed to do another series, they almost managed to do one, but Lucas and Walliams declined due to the condition that the first episode would be commissioned to be 90 minutes long, which they did not want to commit to. If only they'd said yes. But anyway, Little Britain was incredible from start to finish while it lasted, and I couldn't be more grateful that a spin-off of it exists as well.
