They have a similar feel and both are female led action movies. My Name (being a series) has more depth and better fight scenes but Special Delivery still delivers in both action and high stakes car chase scenes.

Both dramas have gentle and warm male leads who love books but have deep scars in their hearts.
The dramas have a similar feel with the script and acting. WTWIF is a slower burn slice of life romance but has a calming and sweet vibe to it, where MAW is a fantasy romcom with a cuter and more lively vibe.

Although they are set in different eras, the movies are similar in their fight against an oppressive regime. They have a similar feel to it, in terms of action and the buildup to the climax. Both have very well shot action scenes and wonderful camera work.
