I know I'm in a minority but I quite enjoyed the the scaled-back 2013 show. Yes, the stage was relatively basic, particularly in comparison to Copenhagen and Vienna, but it also allowed meant that the acts didn't get lost in a wall of LED. Equally, the interval acts, particularly in the final, were actually enjoyable. The Swedish smorgasbord, whilst a little self-congratulatory, was really imaginative, and SDF's cover of The Winner Takes It All was inspired. Finally, Petra Mede was an excellent presenter, having the right mixture of professionalism and well-executed humour, all made possible by her flawless English (and French).
Basically, I think 2013 really showed that a well-executed, professional Eurovision doesn't require a huge budget, and I hope SVT continues this tradition for 2016.
