This is a three-disc set with the first three Jurassic Park movies that starred Sam Neil, Laura Dern, and Jeff Goldblum. The first movie, which of course, is the iconic movie that started it all and was directed by Steven Speilberg starred all of them, the second movie, The Lost World starred Goldblum, and Jurassic Park III brought back Neil and had Laura Dern in what amounted to an extended cameo. I will not spend a ton of time reviewing each movie because chances are, anyone reading this by now has seen them all more than once. I think most people will agree with the notion that the original film is the best of the group, by far, and that the other two, while good, were not great. Jurassic Park III gets dumped on, I think unfairly, did have some good moments, but was a bit cookie-cutter. The CGI quality gets better (obviously) with each movie as the first was made in 1993 before CGI was really revolutionized by movies like The Matrix, Harry Potter, and the Star Wars Prequels. The third installment was made in 2001, so there was a big leap in special effects technology by that point.
Really, the big reason to get this set is the bonus material. There is a ton of bonus content for each movie. The big one is a "Return to Jurassic Park" documentary that has at least one installment for each movie (the first movie has three chapters of it, the second movie has two, and the third movie has just one chapter). There are also deleted scenes, and a lot of behind-the-scenes material for each movie, including archival footage for the original film, the theatrical trailers, and a commentary track on the third movie with the special effects team. So, if you like watching the bonus material, you get hours worth in this set.
Overall, the movies range from good to great. They are definitely not always historically accurate (the thing about a T-Rex not being able to see you if you stand still has been totally debunked, but it makes for good drama) but the movies are not trying to be a nature documentary about dinosaurs. They are well-acted and mostly well-written. The set that I have packages the movies in a folding case with each disc in its own holder. The movies look and sound great in HD. Of course, now they are being released in 4K so if you do not already own them, you may want to opt for that. But, if you have not upgraded to 4k, this is a great way to see the movies. I definitely recommend it.
