I agree about Manny Coto. He should have had Brannon Braga's chair.
But Season 4 was it's best season. After the utter trampling of canon and characters in Season 3, Season 4 seemed polished and better written.
This show's biggest flaw was where it was slotted in Trek canon. Why did they pick that era if they were not going to tie it in properly? Like you said, the aliens shown in Enterprise ruined it and they caused Trekkies to send thousands of letters to Paramount. There was something of a viewing boycott organized, and the ratings suffered. The new" races they introduced:
- The Denobulans: They were co-running Federation outposts and space stations? Before Kirk's time?
- The Suliban: Really? Such beings would have been much more of a threat than the Borg in Archer's time, Kirk's time and even Picard's time. Shapeshifting, genetically mutable beings who have time traveling abilities? You bet.
- The Orion Syndicate: Yawn. From the Shrek planet.
- The Xindi: This was a 5-fer, with the Primates, Aboreals, the Insectoids, the Aquatics, and the Reptilians.
None of these were in any of the later series and that makes no sense. The Xindi attacked earth itself with a weapon of mass destruction, and no mention or record of it in later series? They should have used the Crystalline Entity storyline from TNG and had the Xindi the aliens behind it's origins or something. Earth cant just be attacked in that fashion and no record of it in later series. There is NO WAY they did not know this was a violation of canon, and Trekkies were livid.
Worse yet, was in Season 3 when Archer literally mugged the alien ship that helped him, and stole their warp coil. And they did not even show them going back to make sure they were okay. The entire crew went along with it. WHAT? I lost respect for Archer because of that.
Im really tired of the time travel trope in science fiction. It is no longer seen as something viable (or even possible) scientifically. Every episode which used time travel in Voyager, TNG or Enterprise was silly to me, even if interesting stories were being told. The entire 3rd season of Enterprise revolved around not only the lame and unwanted Xindi but also time travel and the Traveler. Why didnt they have Wesley Crusher play the role of Daniel? He became a Traveler in TNG.
Word of advice to enjoy Enterprise: Watch Star Trek 2009 and Star Trek Into Darkness first.
