For no french people, imagine « doc brown » played by Denis Hooper for the sequels of « BTF » ! It would be a tragic, inappropriate casting that kills the magic of the movie and that's what happens there : it's funny to see that the opening scene exposing the previous story re-shots the scene exactly like « BTF » did it with the new Jennifer ! With this Robin, we have a big, sad potato playing, void of any talent, charm and who fails miserably to do what Lemercier excels ! She really destroys the movie or at least all the scenes she is involved ! You can see that there's much money in the production as the medieval scenes are really detailed ! It's fun to be back to the same locations and meet again the postman ! Sure, unlike « BTF », the time travels aren't not the opportunity to deepen the characters or their relationship as Reno and Clavier do exactly the same fun and chaos than previously ! I don't really understand the motive to this second travel : why Jacquouille just don't give back the necklace in 1193 or why the Duke is ill due to this missing necklace ? It isn't lost in time or in the future as it's hidden in 1193 ??? At the end, it's indeed a crippled sequel, yet funny but without any originality and just plagued by an hideous, unmotivated cave-girl !
