For those confused, this specific listing is for the Season 2 OVAs of Black Butler. :)
I sense these were meant to be filler episodes that instead became OVAs, but after finishing S2 they were very refreshing to see. I enjoyed seeing backstories of side characters, and a first-person episode was an interesting experience.
The Alice in Wonderland episodes were cute, but felt too long. I'd recommend taking the time to watch these episodes, though, as they add a bit of depth to some characters, explain more about the Reapers, and give a very fun 4th wall break.
