Of course you would. It's called an OPINION, not Bible truth, and I'm allowed to say it as much as I want to if it comes up. If Dawn Treader had been an "excellent" film, it would have done better at the box office. The reason it didn't: it was not an enjoyable mainstream movie and never will be. Every time I watch it, I cringe to think of spending the money to support it while it was in theaters, and I also cringe when I think about how I defended the movie before it came out.
Let opinion be opinion and leave it alone, will ya? You're not forced to agree with it, and I'm not forced to agree with yours. In fact, you don't see me posting on people's profiles saying, "You're WRONG cause Dawn Treader was HORRIBLE. <insert personal review here>." Puhlease. If I hated people that much, sure, I'd probably do that to every person that came out in favor of Dawn Treader. But I don't, because I let them have their opinion. I think you should consider doing the same.
