This is an enjoyable series, but the initial blurb made me think overeating would be a major plot point, but besides being the reason why Mike and Molly met and being a topic in a couple of earlier episodes, it doesn't feature much any more.
The later episodes mostly revolve around Molly's hot-and-cold relationship with her conservative and protective mother-in-law, and Mike's exasperating experiences with Molly's liberal family.
I also love the relationships between Mike and his partner Carl, and their relationship with their seemingly-personal waiter Samuel.
But a lot of the topics seem recycled from other shows - it's like watching remakes of other shows in certain episodes. However, it is still an enjoyable show - I did not expect to enjoy it as much as I do. Give it a chance - it's not the best, but it's still a good choice for an average day.
