My summary above is NOT meant as criticism of "I Love You, Goodbye". Many millions of folks love romance novels such as those put out by Harlequin and would adore this film. Yet, sadly, many of these same folks are not the types to watch a foreign language movie. If you love these stories and are willing, however, you'll probably enjoy it.
Lizelle has moved in with a handsome surgeon (Adrian). However, warning signals abound, as although he loves her, his family situation is NOT ideal. He's got an ex-wife who his family adores and a daughter who immediately hates Lizelle. In fact, it seems like everyone hates Lizelle--but she takes it all in silence. Additionally, while Adrian cares for her deeply, he's also a knucklehead who tends to pull within himself when he has problems--and freezes Lizelle out in the process. Into this VERY vulnerable state arrives Gary--Lizelle's old fiancé. AND, Gary is trying to get to Lizelle by dating Adrian's daughter! What will Lizelle do?
As I said above, this plot is pretty familiar for romance novels. And, if you don't like them, I certainly wouldn't recommend this film. Not especially deep but enjoyable. I do wish, however, that the film didn't all rely on Lizelle being weak and not speaking up to demand more from the men in her life or to demand more for herself--it seemed to take forever for her to finally do this. This weakness does undermine the story, though it is still a mildly enjoyable romance nevertheless.
