In Keat's poetry there is spontanity and concentration of thoughts, feelings and emotions.Many of his poems are highly didactic.He was a warm lover of beauty.Hellanic feature are soul of his poetry as in Ode to Gracien Urn and Ode to Psyche references from Greek Mythology are at its peak.
Whereas,in Ode to Nightingale there are features of escapism which shows poet's quest for freedom from weary world.Keats love is Platonic and no moral teachings are present in his poems .Choice of words is superb and refined.
Like all romanataist he is also an idealist who has yearning for freedom and wants a utopian world for him .
I have read several poems of John Keats and all of them are written artistically with full grip over the subject of art.
