It would appear that cousin Oliver has jumped Fonzie's shark. Putting new and fancier ornaments on a Christmas tree has a certain charm, but this was a travesty. The plot doesn't lend itself to any semblance of credulity anymore than that of the first movie i.e. Time and expense versus expected profit from venture (unobtanium, immortality etc.) This is clearly an attempt to capitalize on, albeit, previous commercially successful endeavours in order to satisfy a rather pedestrian appetite for some sort of immediate, short-lived sensationalistic pablum which, all too often pervades the offerings of the day.
