In my opinion, the first was the best, The Lost World was good, and then things went downhill with Jurassic Park III.
When one looks at its sequels, one may see a common pattern especially in science fiction or horror franchises. Jurassic Park, which is my favorite film of all time, is a great example of this in the film industry. This may be why so many in the film industry are trying to bank on nostalgia to try to recapture the original feel through remakes and reboots while not trying anything new. Places, people, film series, everything might seem too big to fail, but rest assured, it can and will eventually fall to the ground, leaving a broken pile of rubble that won't please fans, nor will it bring any new ones. What starts as great thing usually goes downhill until it is a mere mockery of what it originally was. There is a saying, “What goes up must come down.” This is usually a line from a physics textbook on gravity, but in most cases it is metaphorical.
The team will have to be strong, their resolve unquestionable. We need a leader, and surround him with the brightest, the toughest, the deadliest allies we can find.
