I ended up actually liking it. Not liking it enough to own it and rewatch it a bunch, but enough that if they made a sequel I would probably watch it.
I still don't like boxing or MMA in real life but I can appreciate a well shot and well choreographed fight scene in a movie. Luckily for me all the fight scenes in Creed were very well done. I thought they were interesting.
I'm still not going to run out and start hunting for more boxing movies but I'll keep my eyes out in case Creed has a follow-up.
