CGI can be brilliant when placed in the right hands but, as always, with great power comes great responsibility. While most filmmakers can resist the temptation of overdosing on special effects, there’s a few out there who would quite happily shoot themselves up with as much computer imagery as possible and then lie there in a happy stupor, admiring the monsters they have created. Here are the 10 worst CGI moments ever…

Cowboys. Aliens. Bond. Han. Indy, for that matter. The guy who made Iron Man. The guy who made Iron Man 2. (They’re the same guy, FYI.) COWBOYS. ALIENS. If this film were a razor, it would have twelve blades, an Unobtanium handle, a cloaking device and an attachment which provoked shuddering orgasm in every woman within two miles. For a frantic, unashamed wet dream of a film, it’s quite watchable.

Sharktopus, yet another mindless and tacky film from B movie re-enactors the SyFy channel, is completely dreadful. No, really. Completely dreadful. You might be one of the people who likes watching shit films and laughing at how shit they are, but even so the antics of this absurd hybrid may leave you struggling to crack a smile.
