How bad is it? It smacks of a hastily-made attempt to make a few extra bucks from a surprise hit.
Should you see it? Nah.
This is a sequel to a film where an incredibly cheerful couple turn out to be murderous aliens; George Wendt reprises his role, but his wife is now played by Julie Brown. An old-west Arizona town (filmed in California) loses its sheriff, whose head got cut off and has its own burial. Then they elect Wendt to be the new sheriff. He and his wife believe in poetic justice, making the punishment (always capital) fit the crime ironically. There's just not enough laughs and the happy-go-lucky mayhem gets tiresome. Jason Sudeikis makes an appearance and it was written by Mike MacDonald (best known from "MadTV").
