Peace be upon you.
Grand Ayatollah Sayyid Sistani (may Allah protect him):
It does not harm the validity of the fast. However, it is forbidden to use television to watch provocative and immoral films that incite sinful desires and lead to moral and religious degradation for the viewer. Believers should be cautious of everything presented on television and satellite channels, especially parents, who must choose for their children what is beneficial for their worldly and spiritual well-being, and keep them away from anything that corrupts their pure nature or morals. There is no power and no strength except with Allah.
Grand Ayatollah Sayyid Khamenei (may Allah protect him):
It does not harm the validity of the fast. However, it is not permissible for anyone to watch it with enjoyment and suspicion, or if there is a fear of being influenced or corrupted.
May you be successful in all good.
