About two years back, I replayed and beat all three Castlevania games for Gameboy. For the first time, I did it in the order of their release, and defeated all of the bosses of Legends on Standard *without* use of Sonia's Burning Mode ability. (Ridding myself of the thought that Burning Mode was simply a crutch to hide poor boss programming patterns).
With all this in mind, I had a new evaluation of Legends. Some people have said that Legends was a huge downgrade from Belmont's Revenge and wondered what the designers were thinking. Having played all three games in a row, I kept that thought in mind, and came up with an answer.
Subjectively, I still feel it was a downgrade, but not to the extent I once believed. Objectively speaking, Legends had different design parameters. Belmont's Revenge, like The Adventure before it, was essentially a re-imagining of the NES trilogy of games. It took the core gameplay, and remixed it with eccentricities all its own.
So why was Legends so different? I strongly believe it was looking at different core gameplay, namely Rondo of Blood and Symphony of the Night. Think about it. It focused in on the castle, like in Symphony, and brought Alucard to the fore as a major story element. Then, its level design attempts to add exploration and multiple paths with dead ends and traps like in Rondo, and it even has one level with an alternate exit and entry point. Instead of rescuing maidens to get the best ending, you're going out of your way to find the sub-weapon relics--and have to use an alternate hidden stage to get that last one. The thing is, for whatever reason, all of these elements are done as half-measures, which results in meandering levels. I think they were trying to figure out how to fit in and condense the various elements, and they ended up conflicting with one another and ballooning the design.
Still, the game wants to be special with its female lead, excellent booklet artwork, a branching stage, Burning Mode, trap candles, some fancy-looking bosses, etc. Really, this game basically suffered from execution more than anything. Ideas like the trap candles or magic system lack polish, coming off as more frustrating than interesting like they should be. The creative, one-of-a-kind Bloody Tears remix that appears only in this game in stage 1 is truly a highlight, though.
Legends was one of the games that helped renew my interest in the series, though, and it was one of the first games in the series that I owned for myself.
In the end, I don't hate it, and it's not as bad as some make it out to be; but the end result, while intriguing, is somewhat forgettable.
