Best Friends till Death
It is on the maternity ward that Heather Thomas (Olivia Crocicchia) meets Shane Riley (Katrina Bowden - Framed by My Fiance) with these new mums quickly becoming best friends leading to Heather moving in to the apartment opposite where Shane lives with her boyfriend, Alex (Chris Zylka - The Amazing Spider-Man). But whilst Shane is poor she is extremely driven and ruthlessly ambitious with a sense that she deserves to have a better life than she has whilst Heather was diagnosed as being bipolar some years earlier which leaves her prone to sudden moments of rage. Things take a dark turn as Alex doesn't share Shane's driven nature whilst Heather finds him really easy to get on with as well as supportive.
Ignore that one of the characters in "I Killed My BFF" has been diagnosed with being bipolar as the name is not important, what is important is that this movie features two characters with issues which can lead to them acting unhinged and desperate. As such a big chunk of what "I Killed My BFF" is about is watching both Heather and Shane have outbursts from Heather threatening her baby's father with a knife to Shane's attitude to not getting her own way is almost as scary, especially when we witness the lengths she will go to get what she wants. And as such as we watch how these two women can snap in a blink of an eye the question becomes which one is going to murder the other, with the cause seeming to be Shane's boyfriend as Heather starts to have feelings for him.
What this also means is that much of "I Killed My BFF" rests on the shoulders of Olivia Crocicchia and Katrina Bowden with both doing an entertaining job of delivering their characters. For Crocicchia as Heather you get the unpredictable volatility as she becomes dangerously angry extremely quickly, yet at the same time you feel the pain behind the anger which makes her moments of rage emotionally painful. Then you have Bowden as Shane who brings just as much anger to her character but also that facade of being a person going somewhere with her life but is actually conceited, manipulative and, at times, full on evil. It makes for a forceful dynamic having these two strong and at times unhinged characters on screen. But there are other good performances from Chris Zylka as the kind hearted, good natured boyfriend to Kim Baptiste who plays Detective Lund.
What this all boils down to is that "I Killed My BFF" is a pretty decent Lifetime movie thanks to this being one of those movies which doesn't tell you everything at the start and as such whilst the title tells you what happens it doesn't tell you which BFF ends up dead.
