Predictably, Warwick Davis is the standout performer in "Leprechaun 2", comfortably outclassing a mostly talentless cast even if he's mostly given low-tier limericks and one-liners to spout en route to an inevitably underwhelming conclusion where he, Cody and Bridget duke it out for his gold and their lives/freedom. As Cody, Charlie Heath has all the aura of polystyrene, while Shevonne Darkin gives a pretty clumsy performance opposite him. Indeed, the only other actor besides Davis who exudes any tangible personality is Sandy Baron, whose George Carlin-esque mannerisms help make the shifty and greddy Morty one of the movie's two entertaining characters. That's still not enough to really care all that much when Morty eventually succumbs to Lubdan's sly spellcasting, but it's something I guess.
"Leprechaun 2" is bad but inoffensive, never really a slog to watch but almost completely devoid of interest. There are a couple of fun moments that make use of good practical effects work (such as when the Leprechaun brutally excises a homeless man's gold teeth, and another scene in which he rips off a man's finger in order to claim his gold ring) but these fall way short of making up for its glaring deficiency of style and scares. It's an easy but unrewarding watch that makes its predecessor look comparatively brilliant.
