I personally liked it better than the first.

Not only is Men in Black International much better than its trailers would have you believe, but it is the first Men in Black sequel that I felt built on the franchise. It's a very fun movie and I'm sure I will be watching it again!

I’m not into sci-fi and have never seen any of the previous MIB films but I was very entertained and thoroughly enjoyed the film

Better than expected. Well written. Overall a good film.
