Not very good, but at least there was a moment of humor in this one, which is rare for Lifetime movies. They usually take themselves so seriously. If not for the funny line, I would've rated it 3 instead of 4, so it was worth a whole point higher on the rating scale.
The entire basic premise wasn't believable or realistic, so that alone is the reason for the low rating I gave it. But I do wish that Lifetime would use a names database of some kind to discover there are many different first names out there for males and females so they will stop using the same ones over and over again, such as David, Dan, Sarah, Allison, Kelly, Karen, etc. And they need to stop using the same actresses over and over again too, no matter how pretty they might be, such as Helena Mattson. This makes the fourth or fifth LMN movie I've seen her in in just the past two years.
And the amnesia plotline is very old and overdone, yet here it is again, along with a very selective memory - (she remembers her best friend but not her own husband) - which stretches our suspension of disbelief to the max.
To give the small amount of credit where it's due: they DID keep me guessing as to which one - or two - of the three people closest to Ms. Amnesia Victim was/were the villain(s) til the end.
