Thanx, Stranger 
I didn't get bored...I even watched the movie in Stop-and-go modus the 2nd time...so much to notice, also in the background (settings, acting)... I liked allusions to Indo-British artists/writers (Ruskin Bond, e.g.!)
The film had been done with a lot of love for detail.
Reggie's character was the rebellious one, so it is clear that he stands out.
Each of the seven characters had an own personality which - imo - had been shown sufficiently. In a small town like Riverdale and in a friends group, there are - by nature - similarities, so it isn't easy to make the distinctions very distinctive.
There also had been different dynamics inside the group...I like Jughead a lot with his silent love.
To me, Andrew wasn't like a leader figure (I don't know the Archie comics)...his leading came just from being the bandleader, so, his character portray was fine to me.
Kushi's Betty comes across as the observing one, the future writer whom I imagine to write the story we see.
Veronica is the one who has the most to learn...a bit the hard way...it is very obvious when she is genuine and not putting up her attitude...and I liked that one can see that she become gradually more natural (and back to the girl she may have been before leaving for London)...she is also the only one living with quite distant parents (which isn't really good for the soul).
Ethel (I like Dot's singing) is the ambitious one but also loyal to her values...sometimes she is the one to connect the dots.
Dilton could have been a nerd but he isn't...I got quite fond of him.
The Archies did not exactly set the world on fire but the youngsters had enough dedication to cause a stir and blow the fire. It was a light tale about friendship and love and how to take a stand against all odds.
