european vacation ( aka national lampoon european vacation ) be the weak of the vacation film ( the first and third one the most superior of the film ) . while chevy chase and beverly dangelo return a clark and ellen griswold ( with new actor in the role of rus and audrey griswold ) and this time they be give a weak script with very bad dialogue . this cause the pacing to suffer and with the joke not very funny at all . to be more specific and what really cause this film to suffer be the fact that the joke a they be and be just paste together into a cobble together script ) and rather than serve a central plot a the other 3 vacation film have . oh well and they can not win them all . 4 out of 10 .
