Most film critics will tell you that sequels are, as a rule, inferior to their predecessors. By there very nature they are derivative, the bastard child of what was once a good idea. Sequels, especially ones of highly successful films, are almost necessarily cursed with a dearth of creativity, made simply to make money, a cynical perversion of the "art" of moviemaking.
That's why you have to see Leprechaun 4: In Space. A fearless fourth in the Leprechaun horror series, In Space breaks rules that either aren't written yet, or simply could not be broken by celluloid alone. A completely original feat, it was borne not from a good idea, but a very, very, very bad one. It succeeds a highly unsuccessful film, and if there's anything it doesn't lack, it's creativity. And trust me when I say this, L4 (as I like to call it) was definitely not out to make money. Rent it now! Rent it today!
