The effects: great.
The music: great.
The acting: great.
The interpersonal relationships and chemistry: great.
The villains: great.
The humor/comedic moments: great.
Even the continuity with the rest of the franchise and the Prime timeline was stellar.
The believable sounding dialogue and arguments between Pike and Kirk and Kirk and Spock? Enterprise NX-01 and Enterprise Ring Ship models on the desk of Admiral Marcus? Keeping the Eugenics Wars as a late 20th century series of conflicts in spite of catcalls over the years to retcon them as something happening decades later? The mention of Mudd related to the most recent Countdown comic books? Even McCoy's De Kelley-inspired short sleeved sickbay tunic was a fun touch.
