No pun intended - obviously Peter Sellers was no more by that time. But you have a lot of people involved who were there at the conception of the series (and what a story that is - check it out if you can, how the character came to be) ... and yet you can feel that the most important ingredient is missing. Even Steve Martin couldn't step into the (big) shoes ... not easy to fill.
Same is true for Roberto Begnini ... he has done some ... wonderful movies (see what I did there?), but this is not one of them. At least I wouldn't call it that. We have a love interest, we have again players you could be familiar with if you have seen the other movies ... and yet ... there is a big hole .. there is Sellers missing.
On the other hand, if you are able to just go with the flow ... just accept the silliness this serves you ... a good example is the Son dressed as a doctor "examining" the bad guy ... this is beyond ridiculous ... you'll either find it super funny or be super annoyed by it ... this informs how you feel about the rest of it.
The beginning of the movie with the chase scene is the same .... funny or not - your choice ... I've seen worse of course ... but also way better.
