General pattern or isolated incidents? There are exceptions to every rule.

(I hasten to add that I'm not impugning your adaptations, only debating in a general way some of the points you raised. These things tend to get twisted out of context--witness the knee-jerk reactions in the current "bad grammar" thread, where some people leap to the conclusion that vernacular use is being assaulted, despite that no one has argued for sanitizing it!)

You at least do something that few other adapters do: you frequently post your revisions here, where people can offer feedback before things get too set. I'm curious: do you in fact receive much feedback? I confess I don't look at your revised versions, in case I decide to prepare my own adaptations--importing other people's copyrighted changes, even unwittingly, is a quick way to get sued. I'm currently wrestling with that with "The Preacher and the Bear", where I can't get Randy Spark's perfect ending out of my head. Even if I rewrite the buildup, it's nearly impossible to rephrase the punch line.
