Doctor Who

It needs to go back to cheap practical effects and far less CGI. The aliens don't need to be made of papier-mâché but we don't need shots of a spinning TARDIS flying through space or the vortex. Just show it fading and reappearing, like normal. The TARDIS interior doesn't need to be so enormous; the size of that Memory TARDIS from the Sutekh arc was fine. It doesn't need to be the location of a story; just a small backdrop while the Doctor and companions are briefly in transit to where they're ACTUALLY going. Finales don't need giant CGI monsters or fleets of Dalek saucers to "raise the stakes". A single Dalek should continue to pose enough threat to have the Doctor worried.

I was perfectly happy watching Twin Peaks and another dimension was represented by some red curtains and garish knick-knacks. Imagination is fine. Weeping angels being the same statue just moved around, and a different one when they attack, that's effective cost-cutting. The creature you never see because it's always behind someone? That's effective cost-cutting. The swarm of invisible locusts that turn you into a skeleton if you stand in the wrong shadow? That's effective cost-cutting. Limitations INCREASE creativity. Budgets don't need to be enormous. Jaws was scarier in the scenes where you DIDN'T see the shark.
