I am just happy they got out of the past and went to the future. To top it off they hit the future reset button with the burn thing (it was really weird how it happened and all that but.. it did what it was supposed to do.. clean slated the whole universe). So season 3 felt a lot like a "get as far away from s1 and s2 as we can" season. A lot of the characters were shaken up. The setting was changed. Anything that doesn't fit perfectly into cannon or prospects of the future was separated. FINALLY not another bad Admiral. Mission accomplished. I feel the seasons have progressively been getting better too. I still am not in love with the show and think it has a lot of work but it is getting better. Season 4 is going to be a complete clean slate.
I hope it gets away from the season long mystery thing that has happened season to season so far. That is where I see the weakest part of the show. Episode to epsiode it isn't so bad but the season threads are soft af. Season 1 was the whole how to get the mushroom thing to work.. meh.. probably the best of them but inject angry mushroom demon dna into a guy problem solved.. ugh. Season 2 was the red things in space helping you beat the AI.. meh.. saw it coming the whole time and took the easy road out with "just time travel" out so kinda ugh even though it did tie things up. Season 3.. my god.. sad kid blows up all the ships in the galaxy because he saw mommy died and screamed while becoming DNA tagged with crystal planet.. ugh.. double ugh. Just focus on rebuilding the Federation and re-discovering how the galaxy works after the burn next season and maybe have a villian/villian race that can show up from time to time to foil. We don't need a big dot connector to just chase around for the sake of chasing it around.
But all I ask is keep trending in the direction you are going. It is getting a little better each time. Just write good stories and try not to worry to much about the big gotta at the end of the season.
