My first introduction to Holmes was through movies, and I was in for a shock upon reading the books. I'd expected them to be plodding, with events occurring in the vicinity of a rather melancholy Holmes who merely put the pieces together, baffled everyone, and descended back into the crypt until called upon again.
The stories were a surprise, with Watson having a full life of his own (and not being a complete idiot) and their friendship much more natural. The biggest shock of all was that Holmes was human. He wasn't the android which I'd been lead to expect at all. He played jokes, he jibed with his friend - though just in fun rather than out of apparent malice, and he had moods other than 'melancholy at home' and 'melancholy while working'.
The air having been cleared there, my view might be slanted, but in opposition to most other viewers who were slanted. The movies that I saw in my EARLY childhood turned me off from Holmes and Watson for quite some time. Any comparison that I make to them won't be fond memories of what I first saw, and condemning the show to mediocrity for not being what I first experienced. Quite the contrary. The characterizations are refreshing, the writing is good, the actors fit the roles from the stories quite well. The sets are good - not fantastic, but good - but that hardly even draws attention, given the fact that the action very rarely relies on 'how well the entire set fits together'.
Complaints? Only 2. Sometimes the writing seems to get a bit too jolly. Though I'll say that if I'm given a choice between a jovial prankster who happens to be a genius and a brooding robot whose only pleasure in life seems to be abusing his 'friend', I'll take the former. The other is that Sherlock doesn't quite as assiduously avoid women in this series. It's a point so minor it hardly rates as a complaint, but it IS a clear alteration from the original, so I thought I'd point it out since by the end of "The Case of the Texas Cowgirl" it's perfectly clear. (Though, again, SUCH a minor point. They weren't on the case at the time, and in the stories he did say that his lack of desire for female companionship was to avoid distraction - and since he wasn't on a case, or even seeking one at the time of the example I mention, I don't think that's a deal-breaker at all.)
All in all, if you enjoyed the stories alone, the series should be a nice diversion. Sherlock-lite, if you will. If you enjoyed some version other than this series - well, I hate to be tautological, but by definition this will not be that other version. Your mileage may well vary.
they seemed to step right out of books , better then anyone Iv'e seen
since.
