“Lemonheads” (* out of four) was a sour and ugly melodrama about two heroin junkies (George Jonson and Samuel Wyatt) caught up in the hell of addiction and desperately search out their next fix which brings them to the lair of a kingpin freak (William Shockley). Don’t look for more plot than that or much else either. Just because it’s a film about junkies doesn’t mean it has to be so junky itself and (also) boring. Film is recommended only for those who may have thought “Trainspotting” was overrated. Incredibly, three directors and writers are credited for this mess which proves that sometimes more really is less.
