I Know It's A Kids Movie But Still.... (spoilers)
I watched this movie with my 12 year old son and even he picked up on some VERY obvious mistakes. I realize you have to buy into the fantasy of the premise but they should always get the basics right, the 3 main mistakes that annoyed me (and my son for that matter) are:
1: If the kid is such a huge Cubs fan, why did he not recognize the manager when he knocked on his door? (as my son said - 'if Joe Girardi knocked on my front door I would know who he was')
2: The kid made his debut on August 11th - and then went to school the next day!!!
3: They could not decide if the final game was a division clincher (as the manager stated) or the NLCS (as John Candy stated)
These are just silly silly mistakes that could easily have been avoided and this makes for sloppy film making and took away from the enjoyment, and Daniel Stern's character was totally pathetic and NOT funny...
