I thought this sounded an interesting idea but any hopes I had for this movie quickly evaporated within the first horrendously amateur opening scene. Unfortunately it didn't improve, having a horrible 1980's vibe to it throughout.
There is some rank bad acting in this epitomised by the lead Alexandra Paul who is simply dreadful and whose strangely muscular arms shown throughout the film are off putting. The rest of the cast don't fare any better with wooden stilted performance after performance. The dialogue at times is just downright laughable. The subject matter of sex sites is seedy but I suppose it highlights some of the dangers the sad losers who use them face.
Murder.Com just doesn't ring true on any level and if the acting and script aren't bad enough you also have to put up with a truly dreadful soundtrack. I was hoping at least for a decent ending but sadly you don't even get this, just an ending as lame as the rest of the film.
Murder.com is low budget but really there is no excuse for producing a movies as bad as this. I don't normally like giving films 1/10, and solely on the basis I at least managed to sit through it all, I'll give it a generous 2/10.
Avoid with all your might.
