Well, I don't really watch that show all that much anymore, mainly since I'm older, but occaisionally I might go back and watch a recording I made of it years ago, or something like that, and remember the good days when I watched it and almost everything on TV was good.
This show is like the book series, but it adds a whole new set of characters like Jetta, Mac, T-Bone, Cleo, Charlie, and Vaz. And who could forget the Bleakmans, the next-door neighbors of the Howards'?
The stories are simple, yet watchable anyway. Although the humor is aimed for little kids, it's not so bad that it's a Dora-style joke you've just heard/seen.
The last couple episodes aren't my favorite, but that happens with most shows--the writers run out of ideas. They aren't all that bad--just different, if you will.
So, if you have a kid or kids, you may enjoy it if you watch it with them.
Final Words: A decent show that can still be enjoyed.
