Interesting article here on the sonnet by Coleridge:
http://www.sonnets.org/coler1.htm
Note how he damns Petrarch and the form he devised as contrived and forced, and complains about archaisms and inversions. (This was written in 1796.)
Note also his praise of Lisle Bowles as the father of the contemporary sonnet. Bowles is almost forgotten now, but he wrote some fine stuff and his influence on Wordsworth, Keats and that generation was very great.
