Ladies and gentlemen of the 1980s, there will be stop-motion animation. If that kind of thing means anything to you, then Clash Of The Titans - a meaningless title, there are no titans, it's just the gods versus Jake Sully from Avatar - may prove to be a nostalgic disappointment. But for the rest of us who thought Ray Harryhausen's jittery creations looked kind of crappy in the first place, there's a lot of fun to be had with The Incredible Hulk director Louis Leterrier's men-in-short-skirts epic.

Bad: As expected, there are dollops of lazily rendered CGI cities and creatures, the most offensive being a cartoonish, snake-haired Medusa. Ol' hissing-head, however, is still more convincing than Hollywood's action hero du jour, Sam Worthington, clocking up his third enormo-blockbuster in the last year. Movie moguls appear to like Worthington's thick neck and shaved head on their posters, but they don't have to pay to sit through his Home and Away-style intensity and dodgy accents, and it's all here in his portrayal as demi-god Perseus. What passes for plot has something to do with Liam Neeson's Zeus and Ralph Fiennes' Hades deciding they've had enough of mankind - comprising of one single city, apparently - while also giving them plenty of time to work out a strategy and even going so far as to give our hero a divine sword with superpowers. In the logic department, things only get worse from there, and it's best to bypass the section of your brain that deals with reason and intelligence, or you may find yourself wondering if that Scrubs marathon was actually a better way to spend your evening. A strangely brief and unsatisfying finale won't help matters if you find yourself unable to make the leap.

Good: Worthington isn't given much to say, which is pleasant, and there are some nifty grotesque moments as soldiers are ripped in two, hands and heads are sliced off and foul witches torment our hero with a lone, slimy eyeball. Our very own Liam Cunningham - fast becoming the household name he deserved to be ten years ago - has bags of charm to drag the film out of its witless bombast and Brit Gemma Arterton should find a swathe of stateside offers coming her way with all the luminous beauty she infuses Perseus' guardian angel Io with. 

So bad it's good: Our cup runeth over. Fiennes, Neeson, Cunningham, Pete Postlethwaite and Mads Mikkelsen all provide so much ham on screen that Denny's could pack it and sell it. A healthy wage packet may be all the incentive they needed, but how they deliver some of the ridiculous dialogue - particularly Neeson up high on Mount Olympus - without a hint of irony or humour is a testament to their professionalism. There's tangerine tans and eyeliner on the men, heaving bosoms and regal accents on the women, and lines like 'don't look this bitch [Medusa] in the eye...' delivered in glorious seriousness. Lock, Stock... alumni Jason Flemyng's brief, wide-eyed hysterics sum up the entire Clash Of The Titans experience: Short, stupid and shamefully fun.

OMG Recommendation: Go see in 2-D. The film was not shot in 3-D, merely retro-fitted for a post-Avatar audience and it’s painfully obvious with some of the lamest and most anonymous 3-D in recent memory. Save yourself the cash and leave those oversized glasses at home.
