It's a bit special with the narrator but when you get used to that, it works really well. The casting is good and especially in the first 3 seasons, I found the show's plot credible and I couldn't wait for the next episode to start. I found it very funny and I felt entertained.

Unfortunately that was only in season 1-3. I'm not quite sure what happened before season 4 was made but not only do some of the actors look very different - both physically and in the way they act - but I also think the plot of the show changed, and not in a good way.

I only saw the first 7 episodes of season 4 when I stopped watching the show. And I haven't tried to watch season 5 ...

I'd rate season 1-3 with 7 or perhaps even 8 stars. But season 4 only with 4 stars. Season 5 - unknown (haven't seen it).
