Computer-Generated Imagery has consistently helped bring some of the most iconic scenes and characters in science fiction movie history to life over the last 50+ years.
Without this tool, we would have never been able to completely immerse ourselves in the world of Pandora in Avatar (2009), been introduced to the awe-inspiring Tyrannosaurus Rex in Jurassic Park (1993) or found ourselves genuinely empathising with an ape called Caesar in Rise of the Planet of the Apes (2011).
Yet, not every ambitious sci-fi project is blessed with the sort of stunning visual effects which impressively transport an audience into a bold new world. Some are actually so painfully bad that they instantly drag fans back into reality and leave them storming away from the cinema with a seriously bitter taste in their mouths.
It must be said, nobody sets out to craft terrible CGI moments (you'd like to think) and these sci-fi effects can sometimes take years to bring to the big screen. So, it's just a shame that what we ended up witnessing in these ten movies either made us laugh, wince or cry for all the wrong reasons.
