I think the think people who bag the series find it lacking in tech (replicators, shields and the weapons etc) they want more not less.
Sometimes less is more. I think it's a great series and would recomend that those people who don't like it watch it with the mind set that it is a history lesson. Im sure if the series was let to run its course of seven seasons they would have aquired more technolagy.
As for the Vulcans, they didn't want humans to "explore" just yet so I guess that is why they don't help them once they decide to go.
Maybe this new movie will motivate Paramount to produce a new series. What time period would be good to tackle next?
