So, I see Blakes Seven is due to return. But I see one of the things mentioned is the opportunity for much better special effects. And it set me thinking, do we really need better special effects? Yes, some of the old sets were wobbly, and all alien planets were an old chalkpit, but how much does flashy CGI really add? Old Star Wars versus Return of the Clones anyone? Are the recent Doctor Whos better because of the effects? Isn't what really matters, the writing, the storylines, the characters? When I saw an old wobbly spaceship, I knew it was simply a representation to move the plot along, a piece of stagecraft. I didn't need to believe it was real. Ok, it helped not to be able to see the string it dangled from, but that was about as much as I needed. Like most of us, I was born with an imagination and the ability to use it, and I find myself wondering more and more how much CGI special effects, and ever better definition and so on really add to Sci-Fi. Are we doomed to discard plot and characterisation in favour of ever more 'real' spaceships? On the other hand - look at Heroes. Yes, there's a bit of CGI, and flying and stuff, but a huge amount of it is decent old style special effects and make up, and drama... Or am I just old and grumpy?
