Considering all the great movies that came out in '02, a third K-9 movie was pretty ill-timed. How you gonna compete with Star Wars, Lord of the Rings, & Harry Potter just to name a few? Ok, so there's that.
And then, who made the asinine decision to change Mike's nane to Tom?
Furthermore, at least for those of us who really liked the first two movies, an explanation for his name change, as well as at least a comment about (James Handy) Cap'n Buyers maybe retired or died, or somethin', and a comment about Tucci's Sgt. Wells character - I mean something as simple as these two were missed at the retirement party would be been super-easy while going a long way. An explanation for Dooley's name change if only bc of trying to protect his identity or what-ever was really needed.
If not for these erroneous production decisions I might've given this one a 7, 8, or 9. But to ignore the previous 2 movie histories created question marks & blanks, as well as being kind of an insult to the bit of momentum these movies had going, all ending up in some frustration for the series fans.
