Yes. Thanmathra is one of those movies you don't wanna watch again. It hurts more on a second watch because it reminds you of how things used to be in Rameshan's(Mohanlal) family.
I believe this is Blessy's best work. Mohanlal makes us cry as he sings "Ithaloornnu veena" with his voice as well as expressions. The whole cast and crew is amazing. Grab some tissues and watch it. This is a movie that should not be missed.
