The first 20 minutes are comedy gold, with typical Python intelligence, which means smarts combined with pure silliness in surgical precision, elevating the whole.
After that, the movie has 60 minutes of ups and downs, not always overcoming the lack of budget, sometimes overusing the "breaking the fourth wall" joke, or just focusing in a less funny joke just a bit too long.
Still, overall, it's impossible to say the quality isn't good, because for every bad segment, with get an opposite amazing one. Big step forward from the 1971 film.
