Blackadder Back and Forth was, or seems to be, meant as a collector's film for fans of Blackadder, and also as a fun reunion for the actors at the millennium. That is, it started out with the same motif as the other Blackadder series: just to have fun and be funny. Though Back and Forth is only funny as an addition to the other Blackadder's, not by itself. All the other series' could be funny on their own. This movie isn't a disappointment if you realize that it's just a wrap up put together for fun at the turn of the millenium, it wasn't meant to be like the other Blackadders, and it certainly isn't. It's a mere following of some of the characters throughout time, which is funny in itself, especially the part with the Romans and the short skirts.
The only real disappoint I had was the loss of Percy Percy. Even in the "Making of a Blackadder" they seemed to avoid talking about Percy Percy deliberately. I think it's great to see Tim McInnerny as more than one role in the series: Darling and Percy (and Smedly), because he's such a terrific and underrated actor, but I loved him the most as Percy and I miss that character. I know he doesn't want to be pigeon-holed as just one character, and he shouldn't be, but it would have been great to see both Percy and Darling in one film.
