About William Wordsworth's Preface to Lyrical Ballads

As Wordsworth states in his Preface, preparing the reader for what he's going to read, his intentions as writing the Lyrical Ballads were those of creating a new kind of poetry, that filtered emotions by reason, and that used the real language of men, describing experiences that dealt with rustic life, humble individual, and using rhythms that also fitted this way of thinking. He had to explain all this in his Preface because poetry in that time was different from what he was writing. He thought that he needed to write Poetry because poetry is often more read than prose, although both can develop the same themes. Lyrical Ballads (entitled like this to give the image of folklore) contains poems that were specifically written for this, as an experiment in poetry, but some poems had already been written (like the lines composed a few miles above Tintern Abbey).
All this paragraph is just to make one question: Do you really think that the ideas Wordsworth stated in his preface were really fulfilled in his poetry? Because I was studying some of his poems --Lines composed a few miles above Tintern Abbey, Michael, Intimations of Immortality from Recollections of Early Childhood, and The Ruined Cottage (within The Excursion)-- and I'm not pretty sure he fulfils what he states in his Preface. I think Tintern Abbey is the closest to his ideas, and it was written even before than the Preface, the poems he wrote for the Lyrical Ballads are not really close to his ideas. Or what do you think.
