Yes there are good and bad points ... but the good things that spring to mind over the years are:
1. I found out about Skydemon through taliking to one of the other blokes when it first came out;
2. Interesting lecture by a well-known RAF medical officer;
3. EASA information and handouts, when no one knew much about it (I presume that hasn't changed ... ?!);
4. Updates on air law;
5. General chat and exchange of ideas with other instructors and examiners; and
6. Met people I'd not seen for years ...
Oh ... and I got a bit of paper that said I'd attended ...
