The penultimate entry in the Final Fantasy 7 remake series improves on almost every element of "Remake" and adds considerably much more content for better or worse. Without a doubt Remake might have some of best combat you'll find in any action RPG and Rebirth does everything to bolster it without overburdening the player, unlike other parts of the game. The mini-games seem to be a common source of ire among a vocal group of players and understandingly so. Although I personally didn't mind them, even the worst mini-games are worth dealing with just so I could experience Fort Condor and Queen's Blood which are quite addictive and fun. There's always the option to completely ignore a majority of the side-content and jump right into the story without being held back from obtaining great materia or weapons which are mostly tied to the main story.

The ending of the game which controversially subverted expectations and despite still following thru with the original's iconic moment seemed to confound on what exactly I was supposed to take away from the game's resolution. I don't mind an open ended ending that allows for different interpretations but even so I find an issue that I had with the previous entry (Remake) as well. The weight and severity of the moment seemed to be undercut by the complete tonal shift from Cloud as he seems to brush over his own emotions which could either be a result of sheer cognitive dissonance or manipulation by Sephiroth. I understand the original did the same but it also handled the death scene and climax a lot better as well. I feel like Aerith's death should've been given a bit more finality, given the gravity of the situation.
That being said I won't go so far as to say that the developers bungled the ending and I'll be reserving my judgement until I play the final entry in the series as it might expound on the unanswered questions that the finale left us with.
