Not everyone can "understand" this movie - and I think misunderstanding it is the only reason anyone could give it a negative review. Movies like this one - by nature of being made-for-television and made-for-12-year-olds - are outside traditional standards for judging movies. In fact, a lot of the factors that would make regular movies bad, in this case, actually make this movie better: not-so-convincing accents, silly plot, random coincidences, and evil leprechauns. Luck of the Irish isn't about challenging intellectual beliefs or pulling heartstrings - it's the movie to watch with friends (that you're comfortable with) after knocking back a few drinks. And in that context, the weirder it is, the cornier it is, the better.
