I agree that the first two series will never be replaced by anything they try to re-create. Series 3 in my opinion, appeared to be the creation of a masterpiece, finishing off by "clearing up the pieces" so to speak.
I never warmed to Queen of Sheba and couldn't fully get into the atmosphere with following specials. Don't get me wrong, New Sofa & Egg Cup did have great moments, but it really felt like trying to keep a bubble from busting, from start to end.
The main issue I've had over the last 2 specials, is the "camp" acting, especially by Dave. All they have done, is replaced a "dozy dave" with a less confincing camp show host ... in my opinion.
Anyway, we can't bring back the past, so let's see how they approach this season's special? (so long as Jim never changes, I have no big issue)
Bring on a Royle Treat!!
All the best,
Cal
