H-scenes have been apart of Vn's since the very beginning. It's almost expected for them to have H-scenes and I'm sure alot of people do enjoy them.
While alot of the time I tend to only quickly read through a H-scene, as most have little real importance to the plot and can just be skipped. That said If I really like the character I'll happily sit through H-scenes.
But some Vn's get H-scenes right, as some people above have given some examples of Vn's where H-scenes are done well I won't go and list more 'cause I'm lazy.
So yeah, While most H-scenes are boring same same there are diamonds in the rough that can just emotionally blow you away be they humorous, saddening, shocking or just kinda rather hot e.c.t.
