So we come from a mecha anime game review to a very very cutesy anime in Hamtaro, lets see what we can learn from this.

Hamtaro is about a group of hamsters who go on random adventures while their respective owners are not around, meanwhile the secondary plot revolves around Laura's day to day life who is of course Hamtaro's owner.
This show is very innocent, the threat level is extremely low, the cast of characters both human and hamsters are well designed and easy to enjoy. It's hard to find any criticism regarding this anime but equally it's also difficult to praise anything as nothing really stands out as spectacular.
Yes it's a cute series but it suffers from the same problem as Tiny Fairy Snow Sugar in that you can work out what goes on pretty quickly and the rest becomes predictable but unlike Tiny Fairy Snow Sugar the predictable nature doesn't ruin the experience and doesn't prevent you from watching it.
But there is something I've only just realized about Hamtaro; the cast of Hamsters is very similar to the cast of Animal Crossing as many of the hamsters share character traits with the weird animals of Animal Crossing, not only that but Hamtaro predates Animal Crossing by four years, so I wonder how much influence it gave Nintendo's weird franchise.
Final Verdict: It's safe and innocent but also very enjoyable, it will become boring after a while but don't let that spoil the experience before hand, there's no real bad thing to say about Hamtaro.
