What a dreadful adaptation. It reduces the wonderful scope and broad flavour of the novel into something trite, clichéd and formulaic. Stephen Mangan is hideously miscast as Dirk Gently – even Harry Enfield’s performance as the character for the Radio 4 adaptations was better. In common with most other current TV productions, the whole thing is smothered in unsubtle incidental music that is anything but incidental, desperately trying to hammer home the point that this programme is KOOKY and ZANY – “laugh here folks!” – when the rapid-fire humour of Douglas Adams has been all but erased from this Godawful script. Avoid like the plague.
