This anime may be titled Zero's Tea Time, but more accurately it should be Zero's Coffee Break. The synopsis makes it sound as though it's a legitimate spy show, but it mostly takes place at a coffee shop, or follows the main lead during his daily routine.
I have to yet to watch or read anything from the Detective Conan series, so I did not know what to expect. The synopsis seemed interesting, but what was advertized was not what I got. This is not to say it's bad, just be prepared for more wholesome short stories, than action or mystery.
This is police, slice of life, with a little drama and light comedy, although it has no comedy tag on A-P.
PG-13.
A lame OVA spinoff surrounding an "ok character." Amuro was never on the level of being a “beloved irreplaceable character.”
Most of the episodes consist of watching vain meaningless drama stories with a little comedy and action sprinkled in here or there.
Not worth watching. 3/10 overall.
It was simply cute, plot was simple, characters were simple, but there was a lot of cute scenes. Don't expect a lot from it, but still it wasn't a completely waste of time.
