So this is definitely a complete 180-degree turn from all of the other Leprechaun movies in that this is the first film of the series that is a real horror movie. The comedy side has gone almost completely out the window, and this movie takes on a far more darker, serious tone. Warwick Davis is sadly nowhere to be found. Instead, the leprechaun is a growling, bloodthirsty creature that is kind of like an evil Gollum, the Uber Vamps from Buffy, and the crawlers from The Descent put together. The events play out like any similar flick does, in that it is your typical chase movie with the kids getting picked off one by one. And in that regard, it's not bad at all, I have to say. It hits all the right beats and has a few good surprises.
There's really only a few nods to the original films, and I'm not even sure that one of them was a nod, but I like to think that it was. The obvious one is at the end with the line "Fuck you, Lucky Charms!" Got a good chuckle out of that. The other one that might not actually be one was at the beginning when the leprechaun obviously attacked a character and there's a shot of his hand with one finger missing. In all the previous movies, the leprechaun has got a thing for either biting or ripping off people's fingers, but I don't even know if anybody else ever cared about this, so it might just be an homage in my eyes only!
Like I said, as a straight creature feature horror film, Leprechaun: Origins does its job, and does its job pretty well. It doesn't really belong in the Leprechaun franchise, but the fact that it is so different from all the other films makes it easy to separate it from them.
