My all time favorite RomCom, and arguably a movie on my top 100 list, is

 

 

This movie will hit you in all the feels.

Hm well how to loose a guy is pretty funny, sure there others but its the one I can remember having watched more then once in recent years (like last decade)

 

Otherwise old clasics like ghost, grease, nothing hill and the like

 

But really most I watched last few years been when I been too tired to watch fantasy or criminal stuff, so not really notisable beyond ok watches to pass time.
