Leprechaun 3 is superior to and inferior to the first two films in the series.
It does this by having a horrible first act, but an interesting first act. This allows it to pull off the feat. Mark Jones, with the exception of the Leprechaun character, is unable to compose believable conversation even if his life depended on it.As Scott McCoy, John Gatins had some of the worst lines ever. Unwatchable.
After Scott becomes infected with the leprechaun's disease in the middle of the second act, the plot takes a turn for the better, and from that point on, the audience can expect nothing but a wonderful time.
This time, Warwick Davis gets to say practically all of his lines in rhyme, and he's sometimes downright hilarious in the second act.
Without Davis, these movies would be unwatchable. The Leprechaun has a destructive (Review of the film Leprechaun 3) charm that is entertaining to witness.
