Geats was a fun series with glaring issues, but among other things had repetitive, low stakes "protagonist must always win" plots. Ace is as interesting as tap water to boot.
Normally, for a kids show, this can be forgiven but it also had some of the weakest writing I've seen in years. The origin of the MK II powerup is a prime example, but even it's endgame turned the power of friendship into something akin to a religious cult.
If you want good, mindless character driven fun this is the series for you. If you want dynamic writing, high stakes, or even a suspenseful plot? Look elsewhere.
If you like Kamen Rider, it's a good watch. If you're going in looking for the next Ryuki or Gaim, you want be finding it here.
