First of all, Impostora is very good, but does not match up the greatness of Bakekang and Kung Mawawala Ka. Impostora has some holes, but are easily been covered up with beautiful acting of the cast.
The mistakes of the director, Maryo J. de los Reyes, made were all overshadowed by the acting. The mistakes such as too bright lighting and sudden jump from a scene to another, were easily fixed by the dual evil-good role of the excellent Sunshine Dizon.
Basically, the story is about twin sisters separated during their childhood when their parents died. The weaker twin's face became disfigured caused by her lousy stepfather. Years later, she gets a plastic surgery, but was shocked when she found someone else's face on hers.
Both the leads and supporting casts were able to create an acting driven story, this is thanks to the greats such as Iza Calzado and Chanda Romero with Mark Anthony Fernandez in his finest performance yet and the comeback of being a villain of Jean Garcia.
The younger cast were able to keep up with actings of those above. Charee Pineda was excellent as always and Jenica Garcia (the daughter of the great Jean Garcia in real life) was able to surpass the acting criteria for newbies (this was her first acting role). StarStruck winner Mart Escudero was average, but lacks emotion in his scenes.
What's good about Impostora, is that it doesn't linger, or focus, its story on unnecessary character subplots. You have three arcs running at the same time: Vanessa/Sara, Lara and Yago/Karen. In fact, many of the characters are disposable, like in real life, and does not attempt to extend: they meet and then part. I commend the series for that factor!
Overall, if you want something different, if you don't want an all crying series, I suggest Impostora. Carefully crafted by one of the best writers in the Philippines RJ Nuevas, who drafted the superior Bakekang from the pages of Carlo Caparas' comics.
