Writing for
Echoes and Dust, Geoff Topley praised the album, production and performance-wise, and called it "a brilliant album that makes no apologies for the sounds therein. The band are unashamed in not taking themselves too seriously and just enjoy creating music they love, and their fans can appreciate. Superbly polished and produced and not a note wasted, it packs a lot into the run time. [...] Giants & Monsters is a cracking metal album bursting with big tunes [...]."
Classic Rocks Dave Everley compared
Giants & Monsters favorably to its predecessor, citing that the latter was "an obvious desire to not reignite past acrimonies lent it an air of cautiousness". He denied it as a power metal album, classifying it as a "thoroughly modern melodic metal album", as concluded by saying that "this bulked-out line-up could easily have tripped over their own feet, but they've avoided it. 'The masters we are!' Kiske sings on closing mini-epic Majestic. He's not singing about Helloween, but he might as well be." Steel Druhm wrote on
Angry Metal Guy that "Giants and Monsters is a weird collection of styles, and it's only a power metal album about 30% of the time. [...] There's a looseness to the writing, suggesting that the group has become more comfortable working together, and as a result, you get a wide-ranging set of songs covering everything from classic power metal to
hair metal and
stadium rock". He praised the vocals and guitar work, said there are "are no duds present, and every song has its weird charms and endearing quirks. At 52 minutes, Giants and Monsters avoids feeling long despite the presence of multiple 8-minute epics." He finished by calling it a "stronger, more refined album overall" than
Helloween. Michiel Hoogkamer, at
Zware Metal, also compared it favorably to the previous album, saying the overall sound "feels far more consistent, and the album flows more naturally as a unified listening experience." He also praised the "balanced" production and mix for allowing most songs to "hold their own impressively". On the other hand, he criticized "This Is Tokyo" and "Hand of God" as "a bit too simplistic and repetitive". He praised the three-guitar, three-vocal work, commented that "Helloween still sounds best when they go all out: full speed, full variety, full epic grandeur—in both vocals and guitar work" and concluded by saying that "by occasionally pulling back on certain fronts, the band is likely to keep fans from all eras on board". Sam Jones, writing for ''The Razor's Edge'', said the seven-men line-up of the band "has also aided Helloween in championing this massive soundscape where every member gets their due across every song so there's hardly a time where you'll feel something is being neglected or waylaid for another track". He said "their riffs feel more accentuated, organised, whereby the band strengthen that impact". He also praised the "cristal clean" production, because of which "everything regarding Helloween is on fullest display", and commended the band for "restraining" in some moments instead of delivering full power from start to finish. He concluded by saying that the band "blow any naysayers out of the water to deliver a massive-sounding, triumphant record".
My Global Minds Travis Green called
Giants & Monsters "an excellent album overall" and analyzed that is had more "experimental" tracks than its predecessor, sometimes falling into "hard rock and melodic metal territory", commenting that "this is one of the band's most varied albums in quite some time". He praised the guitar and vocal work, but thought that "this is a noticeable step back into more 'normal' quality" compared to
Helloween, also noticing what he saw as "inconsistency" among the tracks. He concluded by calling the album "a bit of a frustrating release, but also one which sums up Helloween as a whole pretty well".
Rock Hard, via Jens Peters, named
Giants & Monsters "their best album this side of the millennium" and said the band "succeeded brilliantly" in making the album reflect their 42-year history. Jürgen Fenske discussed at
Metal.de how much
Giants & Monsters could be seen as a "
Helloween Part II", and concluded that "it all depends on the perspective [...]. There's more mainstream music on "Giants & Monsters" than on "Helloween." However, what the pumpkin heads almost consistently achieve is delivering a cohesive LP. [...] Ultimately, there is once again a top genre representative that is somewhat more focused on consensus and the mass market than its predecessor from 2021". ==Track listing==
