The first film was great.The second was good.I wasn't too keen on the third because it was half-an-hour too short,Jeff Goldblum wasn't in it (it would be nice to see him and Sam Neill in the fourth,if they make a fourth),the T-rex only had a pitiful cameo-role (why?),the spinosaurus was too big to what it was really like in real life,and some parts of the film were really cheesy (ie:the ending).However,the JP3 did keep me entertained and Sam Neill was good.I liked the idea that the 'raptors had a deep form of communication.
Both books are really good. The Lost World is completely different to the film though.
