How do I get 123Movies to play?

I'm encountering some issues with getting 123Movies to play properly. Could you assist me with some troubleshooting steps? I've tried accessing the site through different browsers but it seems to be an issue with the video player itself. Are there any specific requirements for the player, like certain plugins or extensions? Also, I've noticed the quality of the streams seems to vary quite a bit. Is there a way to ensure I'm getting the best possible streaming experience? Lastly, is 123Movies a safe and legal platform to use for watching movies and TV shows? Any help you could provide would be greatly appreciated.
