A question in one of the threads had me thinking about if you are better seeing a movie 'cold' or reading the book or a plot summary first?
Personally I'm someone who sees or reads an idea for a story and just has to understand and know the plot straight away. LOST or Babylon 5 on TV spring to mind has shows that really engaged me in their first couple of seasons and drove me nuts just wanting to understand what was going on. Of course LOST turned out to be crap and was just making stuff up as they went along, but at least Babylon 5 had a plan and followed it through. (Even if it was all rushed in season 4)
As a kid I still remember when 'ET' was coming out and telling my parents I wasn't going to get the book before I saw the movie for a change, so it would be a surprise. I didn't last more than a week before having to buy one of those kids photo story books. I just had to know. (I don't like not knowing)
The Empire Strikes Back and Return of the Jedi both had these large photo book things for sale before the movies came out, they came with a cassette tape. It had a narrator and included sounds and talking straight from the movies. So, by the time I saw the films themselves, I already know who was his daddy and sister, etc.
I do realise I would have been better to wait and see those movies as intended, but I find it very had to pass up temptation like that!
Of course, an example of the other way of doing things would be The Lord of the Rings. In that case I suspect I was FAR better off having read the books first.
