Seeing as it's a continuous story, I'm writing this review to cover both seasons. This series is made by the same guy as Detonator Orgun and Dangaizer 3. It had some potential. The core issues can essentially be boiled down to the series being bloated, whilst simultaneously not knowing what to do with its runtime. For a show that constantly add things to its narrative, it spends way too little time developing/fleshing things out, and too much on its comedy and raunchiness. Having so many things happen offscreen, when half of almost each episodes, and all of some, get spent on things that neither service theplot, nor the characters, is an affront to the audience.

Aside from the aforementioned problems, it also leads to there being narrative creep, abandoned plot points, characters that are nothing more than archetypes, pacing issues, lack of proper worldbuilding, lack of development, lack of fleshing out, a B plot that may as well not be there, mystery bait for the sake of mystery bait, continuity errors, etc, etc.

It also missed out on doing certain seemingly obvious things with what it had. For example, let's take the main mecha of the IP, Gravion. It has human piloted add-ons. The series could've explored themes of trust or even PTSD. The trust aspect from the cast not having enough faith in one another to fire/be fired at the enemy, and the PTSD aspect stemming from the potential harm that they could be facing by being shot at the bad guys/ the harm that their companions could face were they to shoot them at the bad guys. Instead, it does nothing more with it than use it for extra rule of cool points. It's not the biggest deal, but I can't help but feel like a more competent team of writers and a better director would've gone for either of those.

Production-wise, there's not much to talk about. It's pretty average. Although, the song playing during the combination sequence of season 1 is awesome.

Ultimately, trimming all the fat would've resulted in the story being concised, as well as having a wayyyyyyyy shorter runtime.
