Why don't you use Seriesguide app on Android?+1 to Buffy and Angel
I won't tell why you should watch them. Just watch and follow the order after Angel starts.
I made a spreadsheet to keep track of episodes I've watched.
Finished all 5 seasons of "The Wire", I must say if you're into the narcotics or drug stuff you guys definitely watch this, the show quite put a lot good reality of crime and politics.
You must be new here, jk that show has been endlessly discussed on this thread but yea for a week I felt i was living in Baltimore not Pune.
