I'd say that this was a less funny Austin Powers. Mike Myers isn't bad, and there was one part that almost had me in tears, but it tried too hard and didn't really work. Justin Timberlake was funny, Ben Kingsley was hilarious, and dual hockey announcers Stephen Colbert and Jim Gaffigan were excellent. My 13 year old son laughed constantly, and my daughter was um...out of her element (looking back, I probably could have picked something better for her). Between the three of us, dropped around $20, so I'd have trouble recommending anyone else drop $20 on it (or more). Again, not horrible, and some really funny parts, but overall, very....eh.
After five seasons, The CW's incarnation of 90210 is ending. (bigstory.ap.org) I stopped paying attention when the original cast members stopped cameoing, which is likely far, far longer than anyone here paid attention to 90210.
