The hardest thing about rewatching suits is going from the finally back to episode 1
The finally is genuinely such an emotional one and it really shows how the characters have developed thought out the show. Especially with Mike, Harvey and Louis. With them all growing so much and becoming better people for it with very close connections together. Then you go back and watch the first season and Harvey is back to being really cocky and arrogant while still being the best closer Louis is an asshole once again and Mike is gullible and puts himself in dumb scenarios with/ for Trevor.
