If this would have been a fictional serial, I'd have given 'Ram Siya me Luv Kush' 5 out of 5 but it goes on its own track and as a lover of Valmiki's Ramayan, it feels off and I'm forced to give 3/5 to it. But the grandiosity of the set, good star cast, better acting and the mesmerizing soundtrack, it still tends to sway you. If you want to watch it for entertainment purpose, this show is better than almost every serial running right now on any Indian Channels. Good direction is one if the best thing that makes this show shine. But again, the emotional and moral aspect of the serial is top-notch and it ends up delivering a good show and makes me add another star to my rating. It's a 4/5 for me.
A humble request to the makers; you can make it the best adaptation of Ramayan ever by showing true facts not going on with your own script.
