tarkovsky films are all in the journey you should have hung in man!if you can't handle 3 hour films,then forget stalker or solaris,your favourites list is very conservative,loosen up stretch out i thought russians were patient & resiliant,
"RUBLEV"has soul and heaps of it,did you not notice the use of nature,the elements& spirituality,you sure your russian?
rublev was the greatest icon painter 
congratulations the only russian i have encountered who has "bagged" a tarkovsky film. and didn't have the balls to see it through,the bell sequence is magnificent suggest you give it another go who knows you might see the light as rublev did.     cheers from oz.
