I had a far longer review prepared, but it seems Steam won't allow me to go into depth about my opinions about the DLC. So let me lay the basic points.

• Fantastic new story that makes up for the lack of which in the main campaign with two new locations with new missions.
  
• Five new dinosaurs, three of which being hybrids; Ankylodocus, Stegoceratops, Spinoraptor. Olorotitan and Trodoon come as real-life additions. Troodon brings a new poison mechanic alongside it, as it's bite is venemous.
  
• Various new genes to help you adjust a dinosaur to better fit into certain enclosures, helping with those unsatiable giant herbivores. Social genes can even allow you to house multiple T-rexes, I-rexes and Indoraptors together, or lower the requirements for dinosaurs with large pack numbers so you can fit more of a variety into an enclosure.
  
• Good for new players, as the DLC unlocks after four-staring Isla Muerta, the second island in the campaign.
  
• New research projects to help lower the cost of refilling feeders, building and even lawsuits.
  
• New feeder types that require refilling less often, and a new storm station to help protect buildings from storms better.

• The hybrids are generally copy-and-paste in model and animations; Anylodocus is just a Diplodocus with spikes and clubbed tail that clips into the ground, Stegoceratops is just a Triceratops with plates and a spiked tail, Spinoraptor is just a bigger Velociraptor with a small sail who's legs like breaking and clipping into it's body when in a stand-off against other dinosaurs.
  
• A lack of dinosaur additions. The hybrids are at a decent number, but another addition or two on the real-life side of things would have been nice. Perhaps a new small herbivore, or a small carnivore like a Compsognathus would have been welcome additions.
  
• Indominous rex's camoflage gene should have been added free into the game.
  
• The genes in general probably should have been introduced for free since they fix a lot of issues I found the base game has with dinosaurs, enclosures and population numbers.
  
• More unique buildings should have been added instead of 'upgraded' versions of existing ones. New additions could have easily been added free into the game.

Overall I find the DLC worth getting if you enjoy playing Jurassic World Evolution. The story alone is worth the price tag to me, however I can certainly understand if you don't want to pay 15USD for a DLC like this. While I wouldn't demand a 5USD price tag others have I've seen, I can admit 15 might be a bit much for content that is lacking for a lack of words. Even 10USD would have sufficed.
I suggest to wait for when this DLC ever goes on sale to get it. It's definitely something you should get your hands on, if not for the dinosaurs then for the solid story alone.
