I can understand why overall reviews are split for this movie and there are some shortcomings. However, I enjoyed the movie overall. It had enough thrills to keep me engaged.
Positives:
+You want some good Dino action in a Dino movie & this movie delivers some great action! The T-rex River sequence is one of the best scenes in the franchise. The sequences with Mosasaurus & Spinosaurus are unique too.
+Acting was decent. All 3 leads did a good job.
+The pacing is good. I read few reviews saying first half is boring. I thought it moved along fairly well. There are some chit chat scenes but you can't just have 2 hours of non-stop action.
+Stunning locations of Thailand.
+The Drex is truly horrifying. It seems to be a cross between a T-rex & an Alien.
+Dolores aquilops!
Negatives:
- The plot of the movie could have been more fleshed out. It does introduce new locations with some new dinosaurs but overall is not quite a "Rebirth".
- Dialogues could be better.
- The people who are going to get gobbled up are predictable.
- Some throwbacks to past movies are good but there are too many in this one.
- The finale does not match the same highs as some of the previous movies.
If you have very high expectations in the plot/story area then it is probably 50/50. However, the movie is enjoyable despite the shortcomings.
