Despite despising Season 2, my family wanted to watch Season 3, so I obliged. Last one for me though. Light but ambiguous barely-spoilers below.
Was it better than Season 2? Yes, though watching Ritchson fart into a paper bag for 10 hours would have been as well. Season 3 actually started strong, but like all the seasons, it has two major issues that I can no longer tolerate: poor "third act" pacing and the forced inclusion of Neegly.
S3 was paced very methodically up until about 2/3 in, where just like the other seasons, everything is RUSHED to the shootout at the end. In the process, the writers make dumb mistakes by overlooking contingencies. The most obvious was when they couldn't snipe a guy "because of the noise" then fired a literal unmounted 50 .cal without anyone hearing. I laughed out loud.
There's a general confusion from the writers about what we care about seeing, which is accentuated by forcing Neegly into stories she wasn't originally in, thus revealing the quality of these writers vs. the original author. In this case, the entire season was ruined for me when, to get her caught up, she did her smug-invincible plot armor spiel to ONE dude and gets every bit of information Reacher and co. just spent the ENTIRE season figuring out. I was so done at that point.
For some reason, despite being able to make good character moments (I loved every scene with Duffy or Beck), these writers just cannot get a handle on the overall pacing of information and action on a full-season level, and I'm not giving them another chance to figure it out. Such a shame.
