I always get more sad about animals dying in movies than people dying in movies, lol, and this was no exception. I'm still sad that probably all the petting zoo dino babies got eaten.
As for the female lead, I thought she was quite strong! Maybe not as strong as Dr Satler, but she was strong in her own ways, and I liked her. I didn't feel like I needed to "buy" her romance with Owen, because it's something new - they only went on like one date, if I remember correctly? So while they know each other from work, it's not like they were ever friends or anything for a long time and already would have that kind of chemistry. Their budding romance feels more real than any insta-love nonsense most movies try to feed you.
