Guards! Guards

This book came highly recommended as an entry point into Terry Pratchett's Discworld. I found the characters and story humorous, but it felt like a bit of a slog to get through. I eventually found the humour a bit repetitive, although the story was tied up somewhat nicely at the end.

I am curious if it is worth giving the DiscWorld City Watch series another shot. Are there any better entry points to the series as a whole?

What can I say, I have read this book multiple times and it still draws me in and I find new ideas and jokes every time. Its a great place to start reading Discworld novels.
