I'm from the "less is more" school of thought. Being meta (the movie plots echo the filmmaker's journey and relate to CGI as a tool etc) is incredibly uninteresting to me - give me a solid story with consistent, well-written and well-considered characters (both human and dinosaur) any day. You read the long form version of why all of that stuff didn't work for me, so I won't bore you with all of it again. But if I'd been given control of one later in the series? I'd probably aim for a character-driven shipwreck movie, with a small group of survivors coming ashore and following some sort of surprising infrastructure inland. Maybe they discover a skeleton crew from InGen working in the compound illegally, perhaps extracting or continuing to develop the expired programs illegally. That could provide an opportunity for some sort of dino expertise from one of the characters. I'd allow the dinosaurs themselves to return to their animalistic motives and sensibilities. No "killing everything for the sake of killing" monsters, no Raptor buddies. Maybe they even refrain from crashing in every roof, or they'll even stop attacking if they've eaten or the prey proves too elusive. Without even getting into practical vs CG, I'd show the animals in a grounded, impressive way - not flying a camera into their jaws every other shot. But really, the people are key. Give us people we grow to love (or even know, or understand) and show us how they care about one another. That's what makes us care when someone gets hurt or killed. More importantly, that's what makes us anxious when they might be hurt or killed. The human characters are our proxy in the adventure, and the more believable they are the more invested we'll be. The dinosaurs are the wonder, the magic, the threat, and the more believable they are, the more dangerous and real the island will feel.
Those are broad strokes. I'd like to see some restraint on every level, and WAY more thought given to story and characterization. Unlike most blockbuster cheese, I'll buy and watch Jurassic World several times over. Dinosaurs have that kind of appeal for me, that I'll watch them in a bad movie. Bad movie, though.
