Sener Sen is perfect. Meltem Cumbul plays not her film character but a
crafty player playing her character. Timucin Esen is perfect. Director
Yavuz Turgul's story seems to be borrowed from Michael Apted's "Enough" (starring Jennifer Lopez and scripted by Nicholas Kazan). Both "Gonul Yarasi" and "Enough" have the same storyline, in which an oppressed woman ill treated by her psychopathic husband runs away from him taking her (and his) child with her.

It may be said that there is no part for Sener Sen in "Enough". Well,
there is no need for the part of Sener Sen in "Gonul Yarasi", either.
Everything narrated and shown about the character Sen plays is just secondary and does not support the main plot of Gonul Yarasi. Yavuz Turgul could easily omit Sen's character from the story and better focus his camera on Cumbul/Esen relation. In that case, the character of Sumer Tılmaç would get a little larger and deeper and could include (only when necessary) Sen's part, too.

Although the name of Sener Sen is written on the top of the cast, although the camera sees him more frequently than any other character; "Gonul Yarasi" is essentially Cumbul's and Esen's story (the implied love between Sen and Cumbul is just a rifle which never fires in the story) and Sener Sen is just a helpless witness unable to do anything to change the course and the finale of the main plot which is also the main plot of "Enough".

But in order to make justice towards Turgul, we must declare that despite the flaws of the plot (for example, in a more credible script, the psychopathic husband wouldn't tolerate for one moment Sen's giving Cumbul shelter at his home and living together with her under the same roof) "Gonul Yarasi" is much better a film than "Enough" in many ways including credibility and artistic quality.
