Sentinel Ep. Discussion, Anyone?

[krossero]

So, I've been thinking about Sentoo part 1 & 2.  I haven't yet seen them, and I'd like to know what you all think of them.  I know that they're the fodder for many a story, but what do you think of the episodes themselves, as fans of the show?  Did you like them, love them, hate them?  Any pet peeves?  What do you think could have been done better?  Speak, ladies!  This could be a great discussion, I think.  Chat at me!
