There are quite a few of both.
Firstly the positives:
- Everyone plays each other.
- Not too many matches that seem like a mismatch on paper.
- Teams that lose a couple of games early still have the chance to compete.
- Guaranteed 9 matches for India, so the ICC get enough money to keep growing international cricket.
- There was a match or two every day through the majority of the tournament, so that the momentum built towards the finals.
Then the negatives:
- Not enough representation from lower level teams. The qualification was too difficult, and so the goal of making the world cup became unrealistic for most teams.
- There were only 3 matches in the final week, meaning that the momentum was lost.
- Dead rubbers, or similar - 3 teams were effectively eliminated with 2 weeks to go.
- Incomplete rounds - India being 2 matches behind made the narratives and changes in fortune less obvious.
- Pitches were too different from how they've played over the past 4 years, meaning that there was too much of a role of luck in the event.
The negatives are too great to mean that it's a good idea to continue with the same format in my opinion. But, the positives are things worth keeping.
So, using those positives as constraints as much as possible, and also keeping the tournament to the same length, I have come up with a format that I believe will make for a better event.
