Please do. If you are a hardcore SW fan, you owe it to yourself to watch it 1-2 more times. Kylo Ren is an incredibly deep and well realized villain, to start. There are so many nuanced expressions, interactions, and moments of character development that you'll never pick up on with one or two viewings. I'm still picking up some of them with rewatches.
For example, the relationship between Rey and BB-8. I never realized that her first meeting with him is a direct reflection of her own experiences on Jakku.. both are lost/abandoned and share similarities with each other that allow their relationship to grow. "Where do you come from" is essentially Rey looking into a mirror and asking herself the same question. This is also the reason why she can't bring herself to sell BB-8; she seems so much of herself in him (subconsciously) which keeps her from abandoning the little guy. These examples only scratch the surface of the brilliance that was overlooked by rabid fans picking apart each frame to create ANH comparison videos.
Another example is all of Han/Kylo's interactions on the bridge scene. So much is overlooked. The fading of light over the entire scene reflects Kylo abandoning the light side and solidifying his bleak future. The score, which begins with a sweet, innocent tone (reflecting Kylo's remaining love for his family and inner struggle) and finishes with a relentless/intense climax as the scene builds toward Ren murdering Han.
I could go on and on. Brilliantly crafted character development considering the pacing of the film.
