In one of the best episodes in the mini-series, Nigel and Sara go to save the sabretooth cat from extinction... by starvation!
This episode shows further maturation of the show's script writers. Compared to the first, where there were too many characters with too little to do, now the balance is just right, and the Ornithomimus hatchlings add the right amount of cuteness, as well. The actors' acting also has grown stronger: the way Nigel and Sara get saddened that they were unable to save the smilodon cubs was the real tearjerker of the episode.
On the other side, though, there's the increasing dependency and centralization on the T-Rexes as the show's CGI'd stars; not even the sauropods can steal the limelight from them, let alone the microraptors or the elasmotherium (from the episode 2). This reflects that "Prehistoric Park" is stuck between a nature documentary and an action show as far as show genres go (but at this moment of the series it is not readily noticeable), but the drama with the smilodons more than balances this out indeed!moreless
