Since the absolutely groundbreaking days of the late 1980's into the early 1990's, the inclusion of visual effects within science-fiction cinema has absolutely skyrocketed. From the earliest inclusions of VFX such as the near flawless T-Rex in Jurassic Park, to the modern master-strokes of Avengers: Endgame, it would be an understatement to say that the technology has come far within the last few decades.
But as with every technological innovation, it has not been smooth sailing for the entire journey.
You see, for every technical wonder we have had the pleasure to look upon there have been more than enough misfires in equal measure, ranging in poorness of quality from the plain and boring to the downright terrifying to behold.
While there may be a few entries you may be surprised not to see on this list, it should be made clear that this list excludes movies that have only one or two bad VFX shots. So while The Scorpion King from The Mummy 2 was as ugly and out of place as Henry Cavill's moustache in Justice League, neither of these shots necessarily reflected on the rest of the film.
Still, we had to have a few dishonourable mentions, right?
9. Tron: Legacy
Doesn't 'young' Jeff Bridges look absolutely horrifying in this film?
In a disturbing dual-role, Bridges played both Kevin Flynn, founder of the company responsible for The Grid (in which the events of the move take place), and Clu, the corrupt ruling artificial intelligence of the aforementioned Grid. The actor had the misfortune of being one of the first to trial the then novel "digital de-aging", a method in which an older actor's face is remodelled and manipulated to resemble their younger self.
The problem with how this was executed lies within the role of the character of Clu. As Kevin Flynn's near perfect double, the character is supposed to serve as a source of emotional turmoil for protagonist Sam Flynn - Kevin's son - who has been searching for his father for almost twenty years. But the way his face is structured takes any and all emotional investment the audience might have in the character and chucks it straight out the window.
Though Clu appears only in a handful of scenes, it is the detriment to the value of those scenes that really hinders this film.
So what saved it from a lower spot on this list? That absolutely gorgeous light-cycle scene.
