If you've seen a couple different Shounen, Action, Anime then this one does very little to offer anything exciting and original, except some really lame fighting methods (Lady Poison).
Getbackers is a typical shounen anime about two guys who are said to be able to get anything back, which has been taken. What helps them are their interesting special abilities Amano Ginji with the power to generate electricity and Midou Ban with a 200Kg hand grip and also possessing the evil eye.
The show pretty much starts of like a typical anime, by introducing the main characters and giving them an opportunity to wow the viewers with some action. Getbackers is able to capture anyone's attention but as the show goes on, this cheesy anime can easily become tiresome to watch. The fights don't help it at all, with the same fighting methods repeated over and over, without any variety, to the point when even the action sequences get boring. In between all the action are numerous comedy moments, to lighten the mood however this is poorly executed and doesn't add much to the show. Also another issue is the characters and apart from the two main characters (Ginji and Midou) the rest are poorly developed and it doesn't help that the have some pretty lame personalities and special abilities/traits. Another annoyance is when the enemies become allies and the allies become enemies so easily that it just makes it all seem pointless.
There's also the animation that can be described in one word "mediocre". It's obvious that very little effort was put into animating this show, as not even the fights seem fluid and all the chibi didn't help the comedy. Another thing that can put anyone of from watching this show is the horrendous opening and ending theme music, but at least the exciting music during the action can make up for it.
Overall this is a pretty decent anime for the simple-minded anime fan but a somewhat intelligent anime fan would be able to see Getbackers for its many faults. It does manage to incorporate all the standard shounen elements but without adding anything original to make it stand out from the rest. Even though this anime is aimed at teenagers it seems more like a kid's show, with moderate violence, no blood and sharp objects replaced by bright shining lights. So if you're over 12 years old then I don't recommend this.
