If the characters had been able to get over themselves, the viewer would have been able to breathe easier. The long looks – forget your lines? The oh-so-serious weighing of feelings, especially, in Fay – grow up, kid. I think it's called analysis paralysis. Her brother had her number. Where does all that probative introspection get her? It's good she rallied around her mother when needed, but was it really necessary to spin into withdrawal? Lash out at Tom when he calls? She's a baby. Someone really should have taken Tom's temperature. I think he was sick or was he just sleep walking? Just kind of drifts into things, including marriage. Use the brain. Get a pulse. Now, put the two together. The kinky Indian music was too strange. Maybe the mermaid idea was considered an artsy touch as well. These are supposed to be fairly adult people who hold down real jobs. Their courtship and relating revolve mainly around the initial newness of meeting and cohabiting. Pretty flimsy deal they got going here. Not surprising that it doesn't weather the first ill wind that blows its way. I guess their parents failed them along the way, but what else is new? You are supposed to acquire some life skills beyond that on your own. You're grown up now (40ish, in his case), so why can't you handle anything? Where's the strength for someone else? Consumed on little me, actually. Good luck on the marriage ("I'm so happy!"). Unfortunately, it takes a lot more than that. Oh, please finally get with it, or just go back home and settle into sucking your thumb in earnest.
This is a downer about two losers likely to remain that way.
