small group question

Lately I've been considering the dynamics of a small group.  I'm looking to join one at church and think that its important to have a vision of where the group is going.  Previously I was a small group leader so I understand maybe a little more about the importance of having a vision and getting others to see that vision for the group.   There is a college and career Bible study that occurs during Wednesday night church.  Last semester this group, also known as Revolution, met Sunday nights.  It was mostly college aged people, both single and married, along with a few older adult leaders.  Since then things have changed and they are now meeting on Wednesday nights.  I feel that there is no vision in this group.  I feel like meeting is just another thing to check off my list of things to attend during the week.   I guess i'm stuck inbetween a rock and a hard place because I know the importance of meeting together with other believers but are small groups any profit if they exist without a clear vision?
