On my rewatch Surprise is still my favourite episode because I'm a Bangel.
Season 2 is one of my favourite seasons though and it has loads of amazing episode s. I think Becoming part 1&2 is amazing. The death of a slayer, Giles being tortured by Angelus, Buffy sending Angel to he'll, it has everything.
Plus Passions is such a powerful episode as well.
It's a close call to pick a favourite.
I agree!Certainly Surprise is the best Buffy birthday episode I'd say.
I really love " When She Was Bad " : we can see, in my opinion, how being the Slayer, for Buffy, can be very traumatising and how much she can be fragile and very human with the tendency to isoleted herself and the difficult to be understand by " normal people".... These are recurring " leit motiv" and, in my opinion, lays the foundation for season five and seven.... 🙄
And, also, love " The Dark Age" : we see that Giles is not so " perfect" and " immaculate" as we are conviced.... The Watcher was almost creepy 😱 And, first of all, Ethan ( a sort of mix of crazy Faith and Super-crazy Angelus and the insolence of Spike) that give a sparkling touch revealing himself insidious as a demon or worst.... 😀
The Dark Age is really a sleeper episode for me. It tends to divide people though. Think some find it too gimmicky which I can see. But you are right its an important one in exploring Gile's past. Think it does lot of for Jenny's charcter too.
