I think it had potential but It was under-utilised and could have been better "staffed".
I like the inclusion of pro routines but a variety of approaches would suit me better e.g.
Starting the show off
Demonstrating that week's dances (especially early doors when everyone is doing the same few ones)
Giving slots to eliminated/departed pros selectively - and maybe even reprising some of the pro-celeb dances too - "keeping the SCD family alive"
Showcasing new talent/potential future pros - I'd also like to see a "promising couples" amateur slot here - on DWTS they used to run mini-comps for kids and teens who were great IMO - my memory is fading, have they ever had kids on SCD?
I think they could also do worse than copy DWTS in another way and bring in some off-beat dance troupes to perform to guest singers sometimes
Plus mixing it up now and again and wheel out the things that Come Dancing was famed for - formation teams, veteran pros, a bit of (entertaining!) ethnic or folk dancing etc -in other words something for almost everyone!
I know people get fed up with the fillers sometimes but is that because they don't want the show dragging out or because of the dancers/dances used?
