How else should you spend St Patrick’s Day than in the dark watching a preview screening of Jack the Giant Slayer?!  It’s loud, fast and epic fun – Ewan McGregor’s quiff and accent alone make it worth seeing. Total hokum and it had me leaning forward and urging characters to run faster.  There’s a great use of 3D that give the giants-eye-view an interesting twist – not used too much it really made it look great.
