Here's why:
* The series concluded with a final season in 2007. This final season wrapped up the main storyline and provided closure for the characters.
* The ending was generally considered satisfying, but there were some loose ends left. This is common with open-ended series that don't necessarily provide all the answers.
* There was no specific episode designated as the "last episode." The final season simply ended with its final episode, leaving the viewers with a sense of completion.
While "Gümüş" did not have a definite "last episode," the final season served as the end of the series and offered a satisfying conclusion to the story.
