8. Avatar 2
Not only Avatar 2, but there is a very real possibility that James Cameron's plans for Avatar 2, Avatar 3, Avatar 4, and Avatar 5 will all stumble their respective ways to disappointment.
For those who weren't aware, yes, the ever-innovative and forward-thinking Cameron has boldly announced plans for a ludicrous four Avatar sequels. Not just that, but Cameron has already shot Avatar 2 and large parts of Avatar 3.
There's no doubting that 2009's Avatar is a truly revolutionary movie. After the initial 3D boom of the 1980s had died a death, Cameron led the charge for a 3D revival. A revival that now had huge budgets behind it and that had extremely advanced technology that could do justice to the vision of filmmakers. As such, Avatar and its over $2.7 billion global box office haul broke all kinds of records - even if the plot was paper thin.
With the bloom once again off the rose where 3D is concerned, and with it now over a decade since Avatar's release, one has to ask the question of just how much demand there is for one Avatar sequel, let alone four of them.
Given how these sequels are set to cost a combined $1 billion, and add in the current minimal audience interest in a return to Pandora - not to mention the ongoing global situation that's caused Avatar 2 to be delayed to 2022 - and Avatar 2 seems destined to fail.
