TL;DR Review

Birdy the Mighty: Decode is a reboot of a sort for the original series. The OVA was adapted from the 1988 manga, while Decode is adapted from the 2003 manga. Kazuki Akane, the director for The Vision of Escaflowne, directed the Decode television series.

Birdy the Mighty: Decode takes on a much lighter tone than the OVA, especially in the art style. The animation is incredibly bright, to the point where any scenes in the day have a washout effect. The art is also a bit lazy as many none essential scenes lack any sort of detail, and the background is just a simple water paint backdrop.

The cheery opening theme “Sora (そら, Sky)” by Hearts Grow matches the new lighter theme of the series. The ending theme “Let’s Go Together” by Afromania is also uplifting and catchy.

More characters were introduced in the TV version with some tweak to the existing characters. For example, Natsumi Hayamiya, Tsutomu’s female friend and classmate. In the OVA she has a more prominent role and a love interest, while in the television show she is just a minor character. We also get to explore other worlds than just Earth.

Birdy the Mighty: Decode is an enjoyable anime, but its pacing is a little slow. The first arc is a bit boring and annoying as we mainly see our main character complaining a lot. This is a better than average anime and I recommend it to those that are fine with a slow-burn and chill anime to watch. This anime contains some graphic violence and mild suggestive themes/dialogs. Intended for young adults.

Spriggan (1998) Movie Review

Spriggan was initially released as Striker in the North American English translation, as it is the English translation of the word “Spriggan” from Cornish.

Many years ago, an ancient civilization known for their advanced technology once ruled Earth, but were destroyed in the end by their misuse. So, they left messages for later generations in the form of indestructible message plates written in ancient Hebrew, informing them that if they could not find a good use for their creations, they should be destroyed. Various paramilitaries, national armies, and armed private forces began to secretly search for these “mysterious artifacts” in order to be used for their own good and against their enemies. The ARCAM Corporation and their military arm, the ARCAM Private Army, can stop these forces from destroying themselves with their elite secret agents known as Spriggans (or Strikers). The film in an adaptation of the Noah’s Ark story.
