Delightfully camp. Every single story has a helpless but well meaning man trying his best to help a pal out, then ending up in an absolutely farcical scenario and still somehow coming out alright. 

The Jeeves and Wooster stories were a joy. Reggie Pepper was a pleasant surprise, albeit the stories were weaker in comparison. 

Definitely some outdated wording and social mores but nothing that would come across overly offensive so much as well behind the times.

The language Wodehouse uses is so evocative of the characters he's giving voice to - dated obviously, but so entertaining and the characters are very endearing. Reggie and Bertie really do try their best bless them, but they love an obtuse scheme and no back up plan so hijinks always ensue.
