Before

The meeting was not good because people didn't really know what we were supposed to talk about and it went on for too long and nobody made any decisions about anything.

After (Professional tone)

The meeting lacked a clear agenda, ran over time, and concluded without actionable decisions. Consider distributing objectives beforehand to improve future sessions.
