Humor in Star Trek is a fine balance. The heavy humor drivin Trek films ( IV & V) have not been on the top of my list, and I think the silly jokes in VI hurt the over all flow of the film. With the original series, you had fun joke driven episodes such as "Trouble with Tribbles", that fit into the cannon along side very serious dramatic episodes like "Balance of Terror". This worked only when you keept the over the top corny jokes out of the dramatic episodes, and at the same time did not make the hokey episodes to heavy handed in the drama department. "Wrath of Khan" kept it's humor on a very low and realistic level. It's the kind of humor most people encounter or use everyday with friends or co-workers. It's not the "pie in the face" type.
This new film looks to be mixing styles. They seem to want to draw fans of the heavy hitting "Wrath of Khan" type films, but at the same time they are injecting "Row, Row, Row Your Boat", type lame jokes. Not a good mix. If they want to make a Star Trek parody, they should just do that, and call it that. They should not try and trick people who want a hard hitting adventure into thinking that's what they are going to get. In 1967, there was a James Bond movie called "Casino Royal". It was a parody, and billed as such. People who took it for what it was, a light hatred spoof, came away satisfied. People wanting a classic Bond adventure, got upset and some even panned the film for using the 007 logo and Bond name as a trick to lure them in (take a look at the Amazon reviews for the DVD). The 1967 "Casino Royal" did have it's positive reviews, and history shows that the official series of Bond film's producers started to take note, and incorporate more and more corny jokes well into the 1970's and 80's. I am not a fan of that kind of Bond film, and got more and more disappointed viewing the series in order after O.H.M.S.S.
