Walking Dead Season 2

[michealo]

finally watched the final two episodes, not impressed.
i've seen plenty of awful zombie flicks with characters that have more common sense then these morons.
glad to see shane gone, bored of his drama, especially if it gives T-dog more lines.
good riddance to the farm as well.

having never read the graphic novels/comics, does merle ever come back into the picture?

Merle is not a character in the comic. Neither are Daryl or "T-Dog". On the flipside, there are several characters in the comic who do not exist on the show.

Having read the comic since the beginning, I fell off the couch in excitement when Michonne was revealed. Since you haven't read it you wouldn't care, but for comic fans that introduction was an epic surprise.
