Trial and Error with its faults was funny and big improvement. And finally Eli gets some. Though she is a fallen Angel(Supernatural fans) it was nice to see Eli become a man.
It's funny because a lot of people have said that this was a big improvement. They're entitled to their opinion, of course, but it's a sad state of affairs when an episode that focuses around an imaginary battle is an "improvement".

I suspect it's really geek wishfulment with Eli that is behind the "improvement" for many.
