OK, enough has been said about Bryce Dallas Howard's big scene in which she outruns a T-rex in heels.

Jurassic World, which I decided to watch again before renting the sequel, has some bad stuff mixed in with the good.

But the good, when it's good, is very good.

Sure, we've had enough of the "kids in danger" tropes in this series. I mean, that's been the focus of all four Jurassic movies to date. These particular kids -- Gray (Ty Simpkins) and Zack (Nick Robinson) -- are fine as terrified youngsters being menaced by massive pointy teeth, but they don't bring anything new to the franchise. Adults in danger can be just as scary.

And there were some problems with this movie, from dinosaurs playing kickball with a gyrosphere (with screaming kids inside, of course), to the sheer number of superpowers bred into the new villainous dinosaur, the Indominus Rex. (Sure, the T-rex and the velociraptors are scary, but the I-rex is downright evil in this film, as evidenced by its merciless slaughter of several apatosauruses purely for sport.)

And the horrifically extended death of the babysitter Zara (Katie McGrath) is just too cruel. It makes the death of Jurassic Park's money-hungry lawyer -- which was played for laughs, rather than pathos -- look positively benign by comparison.

But there's plenty of positives, too. The escape of the I-rex from its paddock -- while requiring a certain level of stupidity by its captors -- is certainly a tense, well-paced scene. The helicopter mission to the aviary adds a certain level of heartbreak, with the unexpected death of a well-liked character.

And the concept is good, too. After three movies in which dinosaurs run amuck on an island intended to be a theme park, it's nice to see the idea realized. Jurassic World is a thriving, busy tourist attraction, like Disney World but with dinosaurs, and it works both as a setting and as a supply of screaming dinosaur fodder.

As our leading characters, Owen (Chris Pratt) and Claire (Howard) are really, really good. Claire is the corporate yes-woman who discovers that dinosaurs are more than just an "asset" to profit from and control, while Owen is the "bad-ass" soul of the company, viewing the dinos with compassion but still recognizing the violence inherent in their genes.

Irrfan Khan provides heart as Masrani, the park's owner who cares about the welfare of both his guests and his main attractions, while Vincent D'Onofrio gives us a strong minor antagonist as Hoskins, the man who sees dinosaurs as potential tools of the military. Jake Johnson and Lauren Lapkus provide comic relief as star-crossed control room operators Lowery and Vivian.

Oh, and the climactic dino fight is awesomely conceived and choreographed. Wow!

Howard, by the way, continues to defend that scene with the heels. In advance of the opening of Fallen World, she said in an interview that it makes sense for her character, who brings a certain corporate chic to a tropical setting.

Still, I think the T-rex -- which, in the first Jurassic Park, nearly outran a Jeep -- would have gobbled her up, heels and all. I guess I'm glad she defied physics enough to survive, though, because I'm looking forward to her in the sequel.
