Happy Birthday Sarah Michelle
14 April 2007 | by (United States) – See all my reviews

I haven't seen a whole lot of teen slasher movies. In fact this may be the only one I have seen, and it is a fitting tribute of the genre for our birthday girl, Sarah Michelle Geller.

Writer Kevin Williamson follows up Scream with a serious example of just how effective these movies can be if they're well-written, directed and acted.

Sarah Michelle Geller (Buffy, TMNT) and Jenniver Love Hewitt (Ghost Whisperer) fit perfectly together and are supported by Ryan Phillippe (Crash, Breach, Flags of Our Fathers) and Freddie Prinze Jr. Why does that sentence sound naughty? If I had to watch one film of this type, I'm glad this was it.
