Milosz does come across as a little slow & stolid, compared with the eccentric brilliance of Aleksandr Wat, for example. But his other fine qualities outweigh all that. His luminous simplicity, patience, metaphysical hope.
There's a fascinating book of conversations between Milosz & Wat, basically an oral history of Wat's incredible life, in the context of 20th-cent. Polish literary & political history (titled My Century).
