Also like how much more dangerous they make Pandora in the beginning. Where not only does the StingBat attack the compound as soon as Jake rolls out, but Quaritch's introduction to the bashee's and his little speech to all the fresh meat, whilst mowing down trees. All this happens before Jake goes to sleep as his avatar for the first time.
Note: Some things I'll talk about can perhaps be SPOILERS for the movie.
That attack you mention reminds me of something. I'm not sure if you read the original scriptment, but in it there's also a concerted attack by two animals right at the beginning, and there's this feeling that Hell's gate is under constant attack. This made sense given that, as it is explained later, Eywa was acting as a defense mechanism (in the scriptment, Eywa seems not a fully sentient intelligence in my opinion, but a sort of quasi-sentient caretaker, the movie leaves this a bit more open). One of the first things Josh/Jake was told was that he would never get sick on Pandora, since when humans arrived Pandora/Eywa developed resistant drugs to all diseases they brought (and RDA promptly exploited that to sell the new drugs back on Earth). The "twist" is, as we find later, Hell's Gate was under constant attack because humans themselves were thought of as an infection by Eywa, and that concerted attack by two mutual predators (iirc, or at least two animals acting in an unnatural way) happened, like many others, because Eywa was controlling them. The reason I said before that this gave the impression of Eywa not being fully-sentient is that it might have tried to communicate with humanity first in other ways. Instead, the hostile behaviour suggests something that is just acting kind of algorithmically based on some set of inputs (i.e. weird stuff arrives->destroy it) and not really "thinking". It's like Cameron says in the scriptment, "Is she intelligent, this Gaia? ... Sort of."
In the movie it feels like Eywa has more of an actual sentience. Grace says "I'm with her" before dying, they hear the voices of the ancestors when plugged in, it's as if the minds are all in there not just stored but perhaps acting as part of the larger Eywa mind. When Eywa listens and answers the call of the Na'vi, it suggests however a bit more of intelligence, required to understand Josh's pleading. In this respect, the movie version of Eywa seems more consistent with past behaviour. I didn't read the new script yet so I don't know if they mention constant attacks against Hell's Gate, but I can only go by what the movie showed anyway, that's what counts. Also, despite seeming a bit more intelligent in the movie, it's like it's less capable in other respects. Why, for example, did Jake have to travel to the other clans (I assume he only warned nearby ones given the remote station's psionic link range) if they could just warn them through the "network", as they did in the scriptment.
In the sequels, given the behaviour on display in the movie, they may go forward with it being some kind of super conscious mind, a sentient being itself, not just a super glorified defense mechanism. I wonder if they're gonna talk about its origins (or will just explain its origins as just natural evolution...).
