The critics like whatever is in fashion this week.

Nemesis wasn't as bad as people made it out to be, JJ's Star Trek was nowhere near as amazing or different as people made it out to be.

Both are average Star Trek films.

Both resemble Enterprise in many ways.

The tide was turning against Trek around the time of Enterprise and Nemesis and turned onto the reboot craze by the time JJ's film came out.

If the critics decide it's time to stop slagging off Star Wars they will, even if this film is just as bad as ROTS or AOTC.
