After watching the three first episodes, I'd thought I would write a short (p)review. The pilot is basically used to set up the premise, and while it lacks the beautiful polish of the following episodes, it really kick-start the series. And I can forgive the few shortcomings of the pilot.
The following two episodes were beautifully produced (if that's right word) and Sarah Michelle Gellar is perfect in her role. The series also have that hard-to-put-your-finger-on-and-even-harder-to-achieve feeling. I kind of got a "Cruel Intentions" vibe. But just as with Sarah Michelle Gellar, it's a more mature and confident feeling. It's really great.
There's, in my humble opinion, just one flaw with "Ringer". But it's a flaw that could potentially ruin everything. The problem is that while the concept is great, Sarah Michelle Gellar is perfect and the production has that great feeling, the writing seems very sloppy. There are so many inconsistencies and plot holes that I get frustrated. The problem is basically limited to the thriller part of the writing, almost as if that writing was forced in by accountants rather than delivered by the writers.
And if it continues down this path, I think it's going to backfire and ruin everything. This is, of course, only my speculations, but I think that the thriller writing must up to par with the rest. Whether it be a problem caused by money counters or that the "thriller writers" are too junior or have to little resources. Otherwise I think that this series will collapse, and that would really be a shame.
