Lightning has two "meh" songs and one obvious filler, whereas the other two albums don't have this problem.
I don't think Ride the Lightning suffers from filler or meh/boredom. Creeping Death is an impressive and anthemic in your face riff fest headbanger and the other songs have variation, some of them with melodic brilliance. Also: the best guitar leads (harmony and end-solo) are on the Ride the Lightning album, namely Fade to Black. That harmony might be in my top 3 of all time, by any band.
The problem I have with with Puppets is that I miss the melodic/catchy-aspects from its predecessor. Especially shown on the second half. When Welcome Home (Sanitarium) is over I already have the idea "Well, that was that, the rest is only going to be less". Instead of putting emphasis on melody, Puppets, relies heavily on riffs. Now if some of those riffs were less repetitive, and if some of the songs had more melodic passages built in, then it'd be a different matter. As a whole, there’s not much variety, especially the mood feels the same most of the time.
Justice... suffers from the same Puppets syndrome. Most songs are repetitive and monotone, thus a big majority of the album bores me to tears.
Why, it's nothing special, should have gone already
