Excellent adaptation.

Don't listen to the negative reviews

I like movies that are aware of what they are selling... without [any] greater aspirations than to make people laugh and that's it.

If you're interested in the topic at hand, you should just watch it and judge yourself because the reviews have gone very biased by people that didn't even watch it and just hate (or love) the creator. I liked it, it was well written, narrated, and directed and it was about a topic that interests me.
