I was also confused by the inclusion of 'I appreciate' in 21d until I came on here. As Chrise said, it was unnecessary.
Anyway, I did enjoy today's - thought there were lots of excellent clues, including the aforementioned 14, plus 16, 24, and 7d (didn't initially 'get' that one!) Clever misdirection in 3d - took a while to realise it was an anagram.
Don't think anyone else has mentioned the rhyming pair of 12 and 20 across? I also noticed an unusual number of plurals - I counted eight.
