I'd love there to be a Jurassic Park 4, so long as it's nothing like 2 and 3, and is up to the standard of the first movie.
I watched JP1 again the other night, and remembered how much of a great film it is. The effects used look a hell of a lot better that some movies these days, and that was 16 years ago! (speaking of which - it's on ITV2 again tonight)
2 and 3 bored me. And as previously posted by someone, JP2 was nothing like the book.
With all of the original cast (that survived) and as action packed and entertaining as the first one, it would be great. Let's just hope they don't make another stinker.
