You gotta see it from Beverly's POV too though. Two of her few defining characteristics were her compassion and her willingness to go through hellfire itself to save a patient. Both were ingrained in her to the point of stubbornness (as seen in the High Ground) It was those aspects and that stubbornness of her that made it impossible to her to just let Worf die, and his stupid "traditions" be damned (and honestly, I for one find it refreshing to see a 24th century human who doesn't just keel over with unrestricted tolerance when an alien culture's value system clashes with her own)
And really Worf had his responsibilities as a parent (however bad he was at the job) which probably also influenced Beverly's behavior considering she was a single parent as well.
So no, I'm on Dr.Crusher's side here and do not think that she acted wrongly or came off as bad.
It was one of the few peisodes were Riker came off as really good. Measure of a Man was another imho.
Yes an appearance by Dr.Pulaski would have the episode even better...and less black and white, since Pulaski would not have been portrayed like Dr.Russel and she would have definitely sided with the Klingon Perspective.
It would have also been interesting to see Pulaski meet Alexander.
And of course the verbal and philosophical sparring between the two doctors.
(also, while I'm not the biggest fan of the TOS crew, I'd say McCoy would have been on Beverly's side in that argument, and would have had some choice words for Worf)
