No new sci-fi?
Actually the Beeb can do some really good new stuff. Not long ago they did a pilot drama called Being Human, about a werewolf and a vampire who move into a haunted house. It was actually really really good, which probably explains why they never turned it into a series.
Re: Tripods, yes, they should remake all 3 books, I remember that series as well and it was some of the best childrens drama ever to be shown on TV. I'd also like to se the BBC do a *proper* war of the worlds. So far there's only been 1 film that's set at the time of the book but I've not watched it as the special effects for it look like they'd been done on an old Amiga 500, the CGI was some of the most appalling I've ever seen, although the designs for the martians did look really cool.
Martian Chronicles, another classic. Although to be fair the story didn't look into the emotional effects of watching everyone else you know at home going up in nuclear apococalypse anywhere near enough.
And a remake of Blakes 7 would be great, although not sure it would ever get made, a lot of the original storyline now looks far to close to El Gordo's Britain today, the Beeb might be mistaken for political commentary :p
And if the Beeb needs to keep the gay quotient up they could also do J G Ballard's stuff, plenty of manlove in his books.
