Yes I would love to see a sequel, but it I agree no overkill and not too soon. I would like to see everyone back but expand on those relationships. The sequel must be written well and make sense with a good unpredictable story line.
I say no sequel. This was a first and it came in on top of all others at it's first showing. Next time may not be as great. No over kill.
Yes there should be a part 2, but it should be about the ex wife and the married couple.
