The groups I have been part of have usually lasted 30-60 minutes. However , I find individual therapy to be the most helpful.

The one group I participated in was also taken over by one very forceful personality. It almost put me off getting depression help. It also taught me not everything works for everyone. You have to not be afraid to look around for what works for yourself.

Mine was extremely helpful. It was thru a mental health facility. We would have members that would try to hijack the group, but the faciatators were very good about bring things back on track.

I attend a weekly support group which is run by the local YWCA. It lasts for 2 and a half hours. We have check-in, body based exercises, 10 minute meditation and an art project for the day. I have been attending for 2 years now and it has helped me immensely. I have made some very good friends through the group.

Most support groups are between 45 minutes to an hour. The precursor to the group I am in now was 13 weeks 3 hours a day for 5 days a week. It was intense and I came out of it a different person than I went in much.
