I really liked it. I was disappointed that it wasn't like the book, which I loved, but it was a fun monster movie, and Goldblum was awesome in it as expected.
It didn't hold a candle to Jurassic Park, but I can appreciate Spielberg not trying to recapture the feel and tone of the original, because how can you? I also thought Jurassic World was a lot of fun too.
The only legitimately bad Jurassic Park film is Jurassic Park 3. That's just a bad movie with no redeeming qualities. Not even William H. Macy could save it.
Also, The Lost World has Pete Postlethwaite playing the most badass character in the entire series. I think TLW is under appreciated, despite having some cringey shit in it (everything with Malcolm's daughter, despite me loving the idea that his daughter is a little black girl, the setups and payoff for her character is so, so Spielberg). The ending sequence in San Diego were hilariously fun too. Julianne Moore and Goldblum sold that shit and we're having a good time.
