I really like the design of it but hate it's role as a background dinosaur that got attacked by Rexy in almost every scene it's in. They should have found a proper scene to show it in.
I don't think it should have been a jobber to the Tyrannosaurus. It should have gotten the fight with the Sinoceratops and then ran off without getting punked out by Rexy. There was no need at all for that additional Rexy moment.
