As you’d imagine, the eco-hippie, Gaia mother earth stuff is overdone and is faintly insufferable, Cameron serving up some mature slices of cheddar in the vein of the thumbs up from T2 and slushy romance of Titanic whilst the song that plays out over the final credits needs to have every copy on the planet collected together and hurled into the nearest active volcano.
The other half is an intense action thriller that recalls Cameron's legendary work on Aliens and Terminator 2: Judgment Day .
The fact that his earlier films don’t seem to succumb to this ( Terminator , Aliens or even Terminator 2 ) may be less a sign of someone losing some degree of control of his material and more the result of someone who is ambitious, striving to find the perfect combination of spectacle, emotion, entertainment, character, cinema and story.
It's worth pointing out that there is a group of "Cameron regulars" including Michael Biehn (The Terminator, a deleted cameo in Terminator 2 , Aliens, and The Abyss) and Bill Paxton (The Terminator, Aliens, True Lies, and Titanic), and Avatar reunites him with his Aliens star Sigourney Weaver, proving there are actors who support his directing style (Biehn was considered for the role of Colonel Quaritch, but Cameron felt reuniting Weaver and Biehn would remind viewers too much of Aliens).
Unlike other James Cameron movies such as Aliens (1986), Terminator 2: Judgment Day (1991) and True Lies (1994), Avatar just doesn’t have the same rewatchability factor.
To this day, the groundbreaking work of 1991's "Terminator 2: Judgment Day" and 1993's "Jurassic Park" is more impressive.
