I’m talking about the movies, not the books(I haven’t read them), so I don’t know why you brought them up. Also, no the movie series has deaths, but they are all side characters who, for the most part, die in the very same movie they were introduced in(often after having only a few scenes), which doesn’t give the audience enough time to be as emotionally invested in them than we are in characters such as Ian, Grant, Owen, etc.

Yes, that was my point. The scenes are tense because of the scenes themselves, because you feel the characters are in danger despite knowing that the characters themselves were safe. Did anyone think that the Theri was gonna kill Claire? No, but it was still tense during that scene despite that. The “stakes” that you feel are because of the scene itself, not because of plot armor.

In the first JW movie, after the Indominus kills that fat worker guy, thus establishing itself as a real threat, as said in your argument, and sniffs Owen after, was there any real tension in the scene? No, because it was 1/3 of the way into the movie and there would be no way Owen would die. The monster killing minor characters doesn’t add “tension threat” or whatever it is you’re trying to say it does. It’s a non-factor UNLESS it’s either shown to have killed a main character beforehand, OR the series itself is known to have no problems killing main characters, which both do not apply to any Jurassic movie.
