For that one, you should arguably watch it in Japanese with subs; a lot of the message intended got removed or drastically cut down when they localized it. It's not HORRIBLE in English, but it's a very different tone and message - and extremely 90s era cheese.
Otherwise, movies 2 through 5 (Movie 2000, 3: The Movie, 4Ever, and Heroes) can be enjoyed in English perfectly fine. Of those, I personally recommend the third (3: The Movie) and Heroes. 3 has a simple story, but it's sincere, the animation's good, and the last battle in particular is very cool. Heroes is admittedly for nostalgia; I have a soft spot for Latios and Latias.
The rest are hit or miss; Jirachi for example is pretty aimless. I can personally say I enjoyed the 2012 movie (Kyurem vs the Swords of Justice), but I know some don't. It focuses very heavily on the Pokemon, and what battles you get - particularly involving Kyurem - are very entertaining.
