I can see the points that the 3* reviewer is making and I'm sure if this was a dramatisation of a much loved English novel, I would be spitting nails too.
There is also the rather thorny issue of the fact that this was cobbled together out of 'spare' scenes from 'The Three Musketeers' and it does show with a lengthy slide show of scenes from the first film at the start and occasional narrative voice-overs to fill the viewer in.
However, it does complete Dumas' story and it does so in the same amusing and light-hearted manner that Dumas wrote his novel.
I can't speak for period accuracy, but certainly nothing jarred for me.
This is not such a good film as the first, but it is still very enjoyable and occasionally laugh-out-loud funny, and to see the first without this would be to miss out on a lot of the story and some great set pieces.
All the actors are note-perfect and I thoroughly enjoyed both films.
