make the fourth theatrical release ( the one national lampoon take it name off of ) look like a comedy classic . a complete mistake and a sad attempt to capitalize on a once proud franchise . painfully unfunny and unwatchable . even for a tv movie . the cousin eddie character have become progressively less amusing and from the original vacation when it be fresh and unique and through christmas vacation when it be start to wear a bit thin and to vegas vacation where it be actually annoy to see come on screen ( but and in fairness and there be a lot of thing that be annoy to see come on screen in that movie . ) . but this attempt to move the character up to lead status be unfortunate to say the least . the vacation movie themselves meet an ugly death in la vega and and this hope at revive even the thin thread of the series for television be thoroughly misguide . chevy chase and company put together a great trilogy back when he be in his prime while now let just pull the plug and let the title rest in peace . ( one tiny note of interest represent the original audrey griswold dana barron and the first of four actress to play the part and include juliette lewis return to the role 20 year later . one be leave only to wonder . why . ) .
