It is always fun to hear the Brits do accents - they have a long tradition of 'dialect jokes'. It is especially fun when they are doing 'Americans'.
It is special fun (and funny) when the accents are done badly.
This episode features a fabulously politically incorrect 'Red Indian', complete with a tee-pee pitched in the hotel room as well as the title character - a Texas Cowgirl with an accent that includes Georgia, Texas, Sussex and, I believe, several other jurisdictions. An international cast for the price of one performer.
This one has the usual thin plot and emphasis on cleverness. It also has the girl roping Watson for some kinky (PG) fun and Holmes pulling a peace-pipe/murder weapon switcheroo.
This is not great literature of great TV but we enjoyed it! On a per episode basis, it cost us 33 cents and that was most definitely a bargain.
