Fletch 2: Fletch Lives(1989):

While not quite up to the greatness of the first Fletch movie,
this one has its plusses!! With Hal Holbrook as a main character,
along with Cleavon Little who is great in this, this is still a fun
movie to watch and enjoy! It hits on a few subjects that were
in the forefront of the worlds headline at the time! Very enjoyable! B+

From IMDb.com:

I liked the first movie a lot but hadn't heard much about this one,
so I really had no idea what to expect. I was bracing myself for
disappointment and was rewarded with a pretty fun movie. Even
though the story isn't anywhere near as good, Fletch Lives is every
bit as funny as the first movie. I've realized that Chevy Chase can
make any movie work. If you're a Chevy Chase fan, this movie is
worth checking out. My favorite part of these movies is actually
the music, and Harold Faltermeyer does what might have been
his last great synth score for this film. I just love that theme song.
It really makes a huge difference to me, and in the end, it kinda
made me sad that they didn't do more of these films. I'm a big
fan of mystery/comedies, and the Fletch series is one that I think
had a lot of potential that wasn't fully realized. Nevertheless,
this one is enjoyable enough. - namideo
