The extra 3 eps of Baccano were easier to comprehend than the main show, although it loses some of the interesting ideas of the main show.

Shinryaku Ika Musume
Nice collection of comedy shorts (each episode consisting of three "sub-episodes").  These shorts are somewhat more like skits, with some ending in odd situations which get "reset" in the next episode.  New characters etc do get introduced throughout the show however, so there is some meaning to the order that the show is shown.
The ending is a little too serious for the show IMO.  Am wondering if they can keep it up for a second season however.

Nyan Koi
Some interesting ideas, however I feel that the main one (talking to cats) is stretched out for too long.
Apart from this, it's mostly a fairly typical harem type show. (the twins are probably the main source of interest other than the cats)
The story doesn't exactly end here, and they do mention a second season, although none has been announced yet.
